Ya might wanna head over to the S&W forums, and do a search under their "Hand Ejector 1896-1961" forum for "Navy Victory".
If there is specific info, they'll have it.
Serial number? XX out the last couple digits. Lanyard loop? Grips, etc. Maybe a photo or two and someone here can probably give ya some more specifics. Otherwise, they're simply a .38 made for wartime use. But kinda collectible to some. Hence the fakes.
