I actually know very little about the older S&W's, but I believe you have a .38 M&P Victory Model, made 1942-1945. The "V" serial # and "US Property" markings say so. The "GHD" is the inspector stamp of Guy H. Drewry, US inspector from 1937 to 1957. However, the true Victory models were chambered in .38 Special (I think), and not .38 S&W.
Yours also has 38 S&W on it, which might make it a .38/200 (.38 S&W) British Service Revolver, or what is know as a "Lend Lease" gun. I think this was basically the same gun as a Victory model with the only difference being the chambering - .38 S&W v .38 Special. The Lend Lease guns also had US Property and GHD markings on them, and the same V serial #.
There, I told you everything I know about them ...... and them some.
Really you should go to the S&W Forum. Now those guys really know their S&W revolvers.
