A friend sent me a photograph of a commercial pre-war 1911A1 ("C suffix serial number, bright blue, wide spur hammer and no lanyard loop, etc.) that is marked on the right side of the slide "PROPERTY OF THE STATE OF NEW YORK". He thought that it was a National Guard pistol but those would not have been commercial pistols and would have been marked US Property. I suggested that it could have been a State Guard / Militia pistol. Any ideas?
