In this action of tort for the conversion of a motor vehicle, tried before a judge without jury, there was a finding for the plaintiff against both defendants. The case comes to us on the defendants’ exceptions to the refusal of the judge to find for the defendants as a matter of law, and to his refusal to grant certain requested rulings, the substance of which will appear in the course of this opinion.

The bill of exceptions recites evidence tending to show the following. In October, 1957, one Lloyd, an automobile dealer doing business in Maine, sold the vehicle in question to one Power under a conditional sale contract which Lloyd assigned to the plaintiff (hereinafter called Commercial). *624 Upon Power’s default Commercial repossessed the vehicle and received Power’s permission to sell the vehicle at a private sale rather than at public auction as provided for in the conditional sale contract. The parties are agreed that on February 26,1958, Commercial owned and had possession of the vehicle.

At the time of the repossession by Commercial there subsisted between Commercial and Lloyd a “Reserve Agreement” which provided, among other things, that if Commercial should repossess a vehicle under an instrument assigned to it by Lloyd, Lloyd would repurchase the vehicle from Commercial for cash; and that pending such repurchase by Lloyd, Commercial could store the repossessed vehicle on Lloyd’s premises without charge, Lloyd to be merely “a bailee with the duty to safely store . . . and redeliver . . . to . . . [Commercial] on demand.” Pursuant to this agreement, the vehicle in question was turned over to Lloyd on March 2 or 3, 1958. On April 15, 1958, Lloyd brought the vehicle to the defendant Concord Auto Auction, Inc. (hereinafter called Concord), at the latter’s place of business in Acton, Massachusetts, where Concord conducted a wholesale used car market. Lloyd paid Concord $10 to “cry” the vehicle which was on that day sold and delivered by Lloyd to the defendant Stan Cross Buick, Inc. (hereinafter called Stan Cross), which paid the purchase price to Lloyd and gave $5 to Concord. Coincidental with this transaction Concord furnished a form bearing the caption “Title Warranty and Bill of Sale” which was signed by Lloyd as seller, by Stan Cross as buyer and by Concord as guarantor of Stan Cross’s title. The next day Stan Cross resold the vehicle. When, two weeks later, Commercial learned of the sale by Lloyd, it demanded of Lloyd that he pay to it the purchase price and of Stan Cross and Concord that they deliver up the vehicle. A business entry on Commercial’s records indicated a payment by Lloyd to it on May 31,1958, of $90.21.

Preliminary to the discussion of the substantive issues, we point out that it is clear from the record that up to the *625 time that the vehicle was brought to, and sold in, Massachusetts by Lloyd, all agreements and acts involving the vehicle took place in Maine while the vehicle was located in Maine. It further appears from the record that the removal of the vehicle from Maine to Massachusetts by Lloyd was without the knowledge or consent of Commercial. Under these circumstances we think that, although the overt acts which constitute the alleged conversion took place in Massachusetts, according to the principles of conflict of laws we would look to the law of Maine to determine not only the question of Lloyd’s authority to sell the vehicle (see In the Matter of Estate of Everett, 112 Vt. 252, 255; Restatement: Conflict of Laws, § 343) but also the question of the applicability of the principles of apparent authority and estoppel, all of which issues have direct bearing on the property rights underlying this action of conversion. See Langworthy v. Little, 12 Cush. 109, 111; Edgerly v. Bush, 81 N. Y. 199, 203-205; Beale, Jurisdiction over Title of Absent Owner in a Chattel, 40 Harv. L. Rev. 805; Goodrich, Conflict of Laws (3d ed.) § 156; Note, 47 Col. L. Rev. 767; Restatement: Conflict of Laws, § 49 and comment c; id. § 102 and comment c. See also, Restatement 2d: Conflict of Laws, Tent, draft no. 4, April 5, 1957, § 98 and comment g; id. Tent, draft no. 5, April 24, 1959, introductory note, pp. 78-81, and § 254a. Compare Zendman v. Harry Winston, Inc. 305 N. Y. 180, 183-184. Cf. Budget Plan, Inc. v. Savoy, 336 Mass. 322, 328.

Before us and at the trial, however, all parties have relied exclusively upon the law of Massachusetts, and there has been no intimation that the common law of Maine is different from our own. In these circumstances we may assume that the common law of Maine is the same as ours and we are not obliged under G. L. (Ter. Ed.) c. 233, § 70, to make a search of that law. Tsacoyeanes v. Canadian Pac. Ry. 339 Mass. 726, 727-728, and eases cited. 1

*626 Also by way of preliminary we mention that the defendants submitted thirty-four requests for rulings. In view of the limited issues raised we think this number is excessive and that the judge would have been justified in requiring the defendants to refashion the requests and reduce the number before passing upon any of them. See Hogan v. Coleman, 326 Mass. 770, 772-773; Commonwealth v. Greenberg, 339 Mass. 557, 584-585. We shall dispose of the issues without reference to the requests seriatim. See Elm Farm Foods Co. v. Cifrino, 328 Mass. 549, 553.

The judge correctly refused to rule that Lloyd had authority to sell the motor vehicle. Lloyd was merely a bailee for storage until he fulfilled his contractual obligation to buy the car. The fact that Power had given to Commercial permission to resell at a private sale did not enhance Lloyd’s authority by inference or otherwise. Compare Budget Plan, Inc. v. Savoy, 336 Mass. 322, 323-326. The defendants ’ contention that Lloyd had apparent authority to sell the car is answered by the rule that a third person “cannot set up an apparent authority unless he relied on it when he entered into the transaction; and also by the rule that a person who deals with an agent not as agent but as principal cannot set up an apparent authority which the agent may be said to have.” Essex County Acceptance Corp. v. Pierce-Arrow Sales Co. of Boston, 288 Mass. 270, 276. Restatement 2d: Agency, §§ 8, 27. There is no evidence that Lloyd professed to be acting as an agent in the sale of the car or that Stan Cross believed that Lloyd was other than the owner. In such circumstances the concept of apparent authority is not pertinent and the requested rulings regarding it were properly refused.

The defendants’ main contention is to the effect that Commercial’s conduct precludes it from enforcing its legal title to the car against a bona fide purchaser. We have previously considered the rights of a bona fide purchaser from a person to whom a motor vehicle had been entrusted by the owner. See Handy v. C. I. T. Corp. 291 Mass. 157, and cases cited; Budget Plan, Inc. v. Savoy, 336 Mass. 322, 329n. *627 An examination of the cases discloses, however, that whenever the bona fide purchaser has prevailed over the true owner, there have been other elements, in addition to those presently before us, which have entitled the bona fide purchaser to protection upon consideration of common law principles, Simons v. Northeastern Fin. Corp. 271 Mass. 285,290-291, see Handy v. C. I. T. Corp. 291 Mass. 157,163; or which have brought the case within the provisions of an applicable statute, for example, G. L. (Ter. Ed.) c. 104 (Factor’s Act), Jeffery v. M. W. Leahy & Co. 258 Mass. 548, 550. Handy v. C. I. T. Corp. 291 Mass. 157, 163, or G. L. (Ter. Ed.) c. 106 (Uniform Sales Act), Denno v. Standard Acceptance Corp. 277 Mass. 251, 254-256. See also, as to G. L. c. 255A, inserted by St. 1936, c. 264 (Uniform Trust Receipts Act), Associates Discount Corp. v. C. E. Fay Co. 307 Mass. 577, 581-583. All of the cases cited have in common with the one before us the fact that

the person to whom the vehicle was entrusted and by whom it was sold to a bona fide purchaser was a dealer in such vehicles. In each of the cited cases, however, there was evidence that, in addition to the entrusting of possession by the owner to the dealer, the latter either had a general authority to sell the vehicle, Jeffery v. M. W. Leahy & Co. 258 Mass. 548, 550, Handy v. C. I. T. Corp. 291 Mass. 157, 162, Associates Discount Corp. v. C. E. Fay Co. 307 Mass. 577, 582; or was authorized or knowingly permitted by the owner to exhibit the vehicle for sale on its premises. Simons v. Northeastern Fin. Corp. 271 Mass. 285, 290. Denno v. Standard Acceptance Corp. 277 Mass. 251, 252-253. See Restatement 2d: Agency, § 201 (3), and Reporter’s Notes to § 174, Appendix p. 260. In no case in our jurisdiction has the true owner been prevented from asserting his title to a motor vehicle against a bona fide purchaser merely because he had entrusted the vehicle to another, even though the other was a dealer. 2 It is our *628 opinion that no estoppel arises here against Commercial from the mere fact that Lloyd was its bailee for storage pending his purchase of the car for cash. See Royle v. Worcester Buick Co. 243 Mass. 143; Marsh v. S. M. S. Co. 289 Mass. 302; McGeever v. American Natl. Red Cross, Beverly Chapter, 330 Mass. 239. Compare Budget Plan, Inc. v. Savoy, 336 Mass. 322, 325-326 (where further facts, not present here, giving rise to an estoppel could have been found). See, generally, Zendman v. Harry Winston, Inc. 305 N. Y. 180. Bequests based on the premise of estoppel were rightly denied.

Nor does the fact that Stan Cross was a bona fide purchaser for value and without notice render it immune to an action for conversion for having purchased, taken possession of and resold the vehicle. Row v. Home Sav. Bank, 306 Mass. 522, 525. Lehan v. North Main St. Garage, Inc. 312 Mass. 547, 548, and cases cited. Tourles, petitioner, 341 Mass. 305, 308. Bestatement: Torts, § 229. There was no reversible error in the denial of requests predicated on that fact.

The collateral contentions of the defendants that Commercial is conclusively barred from recovery in conversion because it demanded indemnification from Lloyd and because it allegedly ratified the sale by accepting an instalment payment after it had learned of the sale cannot be sustained. There can be no ratification where the seller (Lloyd) neither acted nor purported to act on behalf of a principal (Commercial). Allen v. Liston Lumber Co. 281 Mass. 440, 446, and cases cited. Wedgwood v. Eastern Commercial Travelers Acc. Assn. 308 Mass. 463,468. Compare Bestatement 2d: Agency, § 85. Nor is the acceptance by Commercial of part payment from Lloyd after knowledge of the wrongful sale sufficient of itself to require a finding that Commercial elected to affirm the sale by Lloyd and to relinquish its right to sue for conversion. Without additional evidence such an acceptance of part payment from a wrongful converter (Lloyd) is as consistent with a continued repudiation of the unlawful sale as it is with an *629 affirmance of the sale. Bradley v. Brigham, 149 Mass. 141, 144-145. See Restatement 2d: Agency, §§ 98-99; Anno. 3 A. L. R. 2d 218, 228.

The judge was in error, however, in his refusal to rule that Concord was not liable in conversion. In disposing of the ruling the judge stated that Concord “acted as an auctioneer” and “exercised dominion” over the motor vehicle. The characterization of Concord as an “auctioneer” is not conclusive as to the nature of Concord’s conduct with respect to the vehicle. In White v. Dahlquist Mfg. Co. 179 Mass. 427, 432-433, where the court discussed the authority of an auctioneer it was said, “The word ‘auctioneer’ is sometimes used to designate the crier who simply calls for bids and strikes the bargain at an auction sale.” We think that this defines the role of Concord in the sale to Stan Cross. It does not appear that Concord had any awareness of Lloyd’s want of authority or that Concord at any time had possession of the vehicle. To the contrary it is part of the agreed facts that “Lloyd . . . gave possession of . . . [the] automobile . . .” to Stan Cross after the sale. We do not think that the actions of Concord under these circumstances amounted to such an exercise of dominion and control over the vehicle as to constitute a conversion. See Jackson v. Klinger, 33 Misc. (N. Y.) 758; Restatement: Torts, § 233 (2), 3 and comment b; Harper & James, Torts, § 2.19, pp. 153-154. (Cf. footnote 3 below.)

The case of Robinson v. Bird, 158 Mass. 357, relied upon by the plaintiffs is distinguishable in that the auctioneer, who was held liable, not only negotiated the sale but also “sold the property,” “paid over the proceeds,” less his *630 commission, to the seller, and, it appears, gave possession to the buyer. 158 Mass. 357, 358-359. Robinson v. Bird is of special interest to us for another reason. In it at page 360 Holmes, J., cites Cochrane v. Rymill, 40 L. T. (N.S.) 744. An examination of the latter case shows that, although the particular defendant was held liable in conversion, Bramwell, L.J., uses the following peculiarly apt and homely illustration: “Supposing a man were to come into an auctioneer’s yard, holding a horse by the bridle and to say, ‘I want to sell my horse; if you will find a purchaser I will pay commission.’ And the auctioneer says: ‘Here is a man who wants to sell a horse; will anyone buy him? ’ If he then and there finds him a purchaser, and the seller himself hand over the horse, there could be no act on the part of the auctioneer which could render him liable to an action for conversion.” We hold that Concord’s acts do not render it liable in conversion.

The fact that all parties to the transaction signed the title warranty and bill of sale adds nothing to the plaintiff’s action of conversion against Concord. Bather than being evidence of an assertion of dominion or control over the vehicle by Concord, it was indicative of recognition by all concerned of the possibility of Lloyd’s title being defective, and was a promise by Concord to hold the buyer harmless if that should prove to be the case.

Other exceptions argued by the defendants have become immaterial because of what we have said and we do not discuss them. The exceptions of the defendant Stan Cross Buick, Inc., are overruled. The exceptions of the defendant Concord Auto Auction, Inc., are sustained and judgment is to be entered for that defendant.

So ordered.
