I have in my care a revolver a friend inherited from his grandfather, It is a WWII era revolver. 6 shot; calipers read in the neighborhood of 8mm-.32 Cyl is 1.576 long 4" BBL. The barrel is pinned on & there is considerable play The rest of the gun is very tight. I did advise Josh probably best not to worry about trying to shoot it. The barrel thing just kind of freaks me out. The logo on the grip is drawn out the best I could with paint. Could this be CZ? Any info would be cool. I actually have several other long guns he has too. I'm going to give them a good cleaning for him.
