Victory model revolvers fall into a few distinct categories:
All were made between 1941 and late 1945
The earliest 38 special 4” barrel models were acquired by the US Navy for use by aviators primarily and were marked “us navy” on the top strap or right side of the frame
A bit later, the mark was changed to us property with the inspector initials ( all I know were marked ghd)
The V was to signify hopes for victory in wwII and started after Pearl Harbor ( guns made prior to this are technically not victory models)
Many are seen without the us navy or us property stamp. At the time pistols were considered critical war material and there was a board ( can’t recall the name off hand but it was something like defense procurement agency) and all orders for guns from non military organizations had to go through this agency to get approval and shipment of revolvers ( police departments, industrial complexes with security details even federal law enforcement) which then once approved were shipped no us property marked victories.
By far the largest number were shipped in 38 S&W ( not special) caliber in 5” barrel length as aid to Britain
A very small number ( I think it was about 500) were made with 2” barrels ( do not confuse these with the many British returns which were shortened and chambers lengthened to accept 38 special - easily identified by the lack of the front locking lug under the barrel )
Post war, it seems many of the 4” specials found ways to civilian agencies in law enforcement ( I have seen a good number stamped Seattle police for example, and also some with civil defense markings or the old triangular cd logo decal on them)
For many years a lot of these stayed in government inventory supplementing 1911’s and the Air Force model 15 revolvers for specific uses. Many were used by the army ( together with regular commercial variant model 10’s ) to arm aviators, and as late as the gulf war were issued to some Air Force air crews when the forces built up to the point there were not enough newer guns to go around
