Appellant here seeks reversal of his conviction under an indictment charging him with violation of the Dyеr Act. 1 He alleges numerous errors in the trial below, but we believe only two merit brief discussion.
Appellant first argues that the trial court erred in refusing to suppress certain testimony concerning evidence allegedly obtained in violation of his Fourth Amendment rights. In early March 1971 a White Freight Lines truck tractor was stоlen from a lot in Alabama. On April 10, 1972 witness Moel-ler, a Los Angeles police officer with over ten years experience investigating heavy equipment thefts, became suspicious of a “ratty”-appearing truck parked at a truck stop in Lynwood, California notorious as a “haven for stolen heavy tractor trailer equipment.” Together with an assistant, he investigated the vehicle and obtained its engine, transmission, and license numbers. A later check revealed that the chassis of the truck undеr investigation came from the vehicle stolen in Alabama and that appellant claimed to be its owner. At his trial appellant moved to suppress all testimony concerning this investigation of thе truck’s identification numbers, arguing that the procedure used by Moeller constituted an unreasonablе search forbidden by the Fourth Amendment. After the required hearing, the trial judge denied the motion.
In a line of cases following United States v. Johnson,
inspectiоns of motor vehicles performed by police officers, who were entitled to be on the property where the vehicle was located, which in no way damaged the vehicles and werе limited to determining the correct identification numbers thereof
Appellant also objects to the trial judge’s handling of the recent possession doсtrine. Because no objection was raised during the trial, to the extent these complaints relаte to the content of the charge we may review only for “plain error.” Fed.R.Crim.P. 30, 52(b). We find no such errоr here. Relying on United States v. Hale,
What constitutes recent possession is not capable of exact or precise definition; it varies with the circumstancеs of each case and, for these reasons, it is often said that the question is one of fact for the jury. We agree with these principles. However, it is incumbent upon the trial court to determine whether there exists sufficient evidence to support a finding of recentness by the jury. . . . There is a certain period after which an inference of guilty knowledge cannot be rationally inferred from unexplained possession. Whether this period has expired is a question for the trial court to determine before giving the case to the jury.
After careful consideration, we find appellant’s remaining contentions to be without merit. Accordingly, the judgment is affirmed.
Notes
. Appellant was cоnvicted on a count charging violation of 18 U.S.C. § 2313, which’ provides :
Whoever receives, conceals, stores, barters, sells, or disposes of any' motor vehicle or aircraft, moving as, or which is a part of, or which constitutes interstate or foreign commerce, knowing the same to have been stolen, shall be fined not more than $5,000 or imprisoned not more than five years, or both.
The jury acquitted аppellant on a count charging violation of 18 U.S.C. § 2312.

See
United States v. Hale,
supra
(six months); United States v. Martinez,
. The judge’s charge included the usual language instructing the jury that the longer the period of time since the theft, the more doubtful is the inference that may reasonably be drawn from possession.
