George, J.
(After stating the foregoing facts.) The motion for new trial raises three questions. Upon the trial the court *512charged the jury as follows: “Equity jurisdiction is established by the law for the protection and relief of the parties, where from any peculiar circumstances the operation of the general rules of law would be deficient in protecting from anticipated wrong, or relieving for injuries done. Equity is ancillary, not antagonistic to the law; hence equity follows the law where the rule of law is applicable, and the analogy of the law where no rule is directly applicable. lie who would have equity must do equity, and give effect to all equitable rights in the other party respecting the subject-matter of the suit. Equity seeks always to do complete justice; and hence, having the parties before the court rightfully, it will proceed to give full relief to all parties in reference to the subject-matter of the suit. ” The error assigned is that the charge, while correct as abstract statements of law, was inapplicable to the issues made by the pleadings and the evidence, and tended to confuse the jury. It may be true that the plaintiff was compelled to resort to equity for his remedy only. Nevertheless, it is difficult to see how the charge complained of, which is merely a statement of certain equitable maxims, could confuse the jury or prejudice the plaintiff’s case. Especially is this true in view of the fact that the court specifically instructed the jury that the plaintiff was entitled to recover, and furnished a standard by which to measure the plaintiff’s damage. We do not hold that the plaintiff can complain of an instruction embodying the general maxims of equity, in virtue of which alone he was enabled to obtain relief. It is sufficient to say that the instructions given, under the facts in this case, will not afford cause for new trial.
2. The second complaint (raised in several grounds of the motion for new trial) is that the court furnished incorrect instructions on the “measure of damages.” The plaintiff elected to demand a verdict for damages, alone, and the court instructed the jury that the plaintiff was entitled to recover “the highest proven market value” between the date of the conversion and the date of the trial. The insertion of the word “market” before the word “value” in the charge is said to be erroneous. Section 4514 provides: “In estimating the value of personalty unlawfully detained, the plaintiff may recover the highest amount which he can prove between the time of the conversion and the trial.” Our attention has not been called to a case in which the court has *513expressly approved an instruction in which the word “value” is qualified by the word “market.” Conceivably it' would be difficult to apply the qualification in all possible cases. For instance, an article of personal property may not have a market value, in which event it would seem that the cost of production may be inquired into, as in the case of breach of contract. See Sizer v. Melton, 129 Ga. 143 (7,8), 151 (58 S. E. 1055). In this case the plaintiff purchased the property for the purpose of resale. There is.some evidence tending to show that it was purchased as junk, and that the purchaser intended to resell the machinery as junk. The defendant in this case also purchased the property for resale. Neither the plaintiff nor the defendant desired the-property for any other purpose. All the evidence in the record refers to market value. There is not a suggestion that the property could not be sold for its full value. The entire evidence on the question of value relates to market value. If in any given case the charge may be said to be erroneous, it is certainly not inapplicable or inaccurate in this case.
3. The third assignment of error is that the verdict is without evidence to support it. It is insisted that the allegations made by Shartle Bros, in the trover suit against Pynetree Co. constitute admissions in judicio, and that the verdict for less than $5,000, the value placed upon the property by Shartle Bros, in the trover suit, is unauthorized by the evidence. We do not think that the allegation made -by Shartle Bros, in the suit against Pynetree Co. can be held to be conclusive upon Shartle Bros, in this case. Between Pynetree Co. and Shartle Bros, the allegation was an admission in judicio. The plaintiff in this suit was not made a party to the trover suit. In Harris v. Amoskeag Lumber Co., 101 Ga. 641 (29 S. E. 302), it was ruled: “Admissions of matters of fact in pleadings operate as estoppels only as between the parties to the cause in which they are made, and their privies.” We think it a sound principle that an admission in a pleading is conclusive only between the parties and their privies and for all the purposes regarding the issue arising from that particular pleading, unless acted upon so as to work an estoppel. In the present ease Shartle Bros, did not in their answer admit the value of the machinery to be $5,000 or any other stated sum. The answer is presumably responsive to the petition. With respect to the plaintiff in this equi*514table suit, the allegations in the trover suit — the prosecution of which was enjoined — stand on the' same basis as extrajudicial admissions.
4. Is there any evidence to authorize the verdict of $4250 ? It appears that the plaintiff in this suit purchased the property about a year before the sale to the defendant in this action, for $3500. The plaintiff himself sold the property to the defendant for $4250. A term of the contract obligated the plaintiff at his expense to place the property on boárd cars. The evidence indicates that this cost was considerable. The plaintiff was relieved of this obligation under the contract; the property was loaded by and at the expense of the defendant. The effect of the verdict 'is to charge the defendant with the original contract price plus the cost of loading the machinery. The president of the defendant company testified that junk had not advanced in price, but on the contrary had declined, since the date of the purchase of the machinery. He further testified that he was experienced in his line of business, that he had not been able to sell the machinery at a fair price, that the machinery was still in his possession, that he was ready to sell it at a profit, and that he could not do so. He indicated that by “profit” he meant fifteen per cent, upon the cost of the article. He also testified that in 1915 he sold a similar machine, but in good condition, for $9,000; that on the date of the purchase and since to the date of the trial such a machine was worth fifty per cent, more than in 1915, or $13,500; “that in my opinion is the maximum value of a machine of the kind in question after it is overhauled and offered for sale. ” He' estimated that it would cost $10,000 to place the machine in condition; $5,000 to place it on board cars and deliver it in his yards, and $5,000 for the actual repairs. From this evidence it is deducible that in the opinion of the witness the machine was actually worth $3,500. His testimony is positive that at the time he purchased the machine it was not worth more than $4250. It is true that several witnesses testified that the value of this machinery was greatly in excess of $4250. The opinion of these witnesses was in each instance based upon the value of the machine after it had been overhauled. That it would cost approximately $10,000 to overhaul the machinery seems to be conceded; but allowing $10,000 for this purpose, the evidence for the plaintiff would have authorized a *515verdict greatly in excess of $4250. From what we have said above the verdict is not, however, without evidence to support it.
Judgment affirmed.
All the Justices concur.
