Navy-marked Victories are more coveted by collectors than the standard military issue Victories, as there is a scarcity factor. They were made under Navy contracts only for about one year from mid-1942 to mid-1943. After that, those which went to the Navy had just the typical US property markings, as they were made under Army contract. There are varying estimates of how many Navies were made, but 85000 seems to be the accepted number. Some were pre-Victories. The highest Navy marked serial number is approximately V265,000 with a few higher than that known to exist. By the way, most .38 Special revolvers made during WWII went to the U. S. Navy, mainly for use by flight crews. One of the roles of the revolver in Navy flight service was for use as a distress signaling device using tracer ammunition.
I would suggest you obtain a factory letter to establish that it was shipped to a Navy facility.
