Welcome to the forum. You have 3 butt shots of 2 different guns then 2 right side barrel shots of the same gun I believe. Post pictures showing all of the gun, left and right sides, along with the serial number of each so we can tell which is which
Welcome to the forums from the Wiregrass! I agree with Jonesy that we need additional and better pictures. However, I was able to discern a couple of things from the pictures you posted. I believe you have 2 .38 Military & Police revolvers. The older .38 Special one with the 265579 serial, half-moon front sight and mushroom shaped extractor rod knob is from around 1915-16. The second one appears to be a .38 British Service Revolver from WWII. I can see the barrel has been shortened from the original 5" and a ramp-style front sight installed. It likely says .38 S&W CTG on what is left of the barrel. On the butt next to the serial is the hole for a lanyard ring, WB (initials for Waldemar Broberg, the ordnance inspector) and a flaming bomb ordnance acceptance stamp. This gun was likely made in early 1942 before the Army went to V prefix serial numbers. That's about the best we can do without more pictures.
