During the war most arms manufacturing was busy in the war effort and S&W was no different. These revolvers were 'no frills' handguns and originally were produced with smooth grips like the ones shown in the lower right of the picture.
These guns were sold to the Navy and Army and used mainly for security on military posts, ports and military manufacturing plants, they were also used by air crews and pilots even up through Vietnam.
The picture here shows a WWII air crew all carrying the Victory Revolver. Also many thousands were made and 'leased' or loaned to the British, Canadian and Australian governments. The ones made for U.S. use were chambered for 38 special while most if not all for Commonwealth countries were chambered for 38 S&W which is basically a short version of the 38 special.
These revolvers were all called Victory Revolvers and are easy to spot due to their "V" prefix in the serial number. Many times you will find them missing the lanyard ring as surplus guns were reworked to look 'civilian' and the hole may even be plugged to hide the original mounting point on the butt of the revolver.
I have a couple of these revolvers one was made in 38 special and is in excellent condition.
The one shown in the post yesterday was first chambered in 38 S&W (The CTG was short for Cartridge) and more than likely was 'leased' to England or Canada and like most returned to the US after the war where the government sold them to the civilian market.
The 38 S&W has a bore of 0.361 while the bore of the 38 special is 0.358 (or .357 thus the origin of the 357 mag) so it is slightly larger however this particular gun is very accurate especially with lead bullets, the action is smooth and overall an excellent shooter.
Side note, my experience has been that any Smith & Wesson 38 of this era (and prior) is that it is more accurate with lead bullets because that was what it was designed to fire, even police used lead bullets mostly up through the 1950's and in fact this revolver is the father of the Model 10 which was a police standard gun (along with Colt) till the early 1980's
Because this gun has been re-chambered it is not original and is at the lower end of the price range for these revolvers ($200-$300 range) I did not feel the need to find period correct grips and just left the stag grips like I found it at a gun show a few years back.
Now for a little 'Duke Rant'..... Those of you who are astute will notice in the first picture as well as the last couple of pictures the firearm is loaded. You can either see the cartridge heads or the bullets in the chamber. The reason I mention this (beside the fact it makes liberals lose bodily functions) is because it kind of gripes me so many times when watching a gun video someone has made, they go out of their way to show it is unloaded and safety checked like they think it will go off in the camera and kill someone through the computer. Now I am all for safety especially when doing a function check or cleaning but give me a break, taking pictures will not cause an accidental discharge. An unloaded gun is nothing but a paper weight and anyone who can't talk about their gun or do a video or take pictures without the need to impress upon me that it is unloaded may I suggest you need to either find another hobby or learn better control but that is just me, you are responsible for your own actions.
Remember, I always treat a gun as if it is loaded because it is.
