And might have been owned by a Korean War vet, but highly unlikely was carried/used in the war.
This type of handgun was never an item of issue for the military
In general the military frowned on use of personally owned handguns ( some higher ranking officers could get away with it at times)
Also the long barrel and heavy weight of this type revolver would be impractical for military use, as other 6 shot revolvers with shorter barrels and much lighter in weight were available and easier to carry. As an old soldier myself, anything you can do to lighten the load you carry is welcome!
