Nice guns, I think you'll find the ones that actually sold in any military 'PX' were not marked, as the 'PX' actually is still 'US property??? so we were told.......but the commercial version guns send to those countries were indeed ' foreign ' proof marked,seen British and Italian as well.. A GI living off base, could have picked one up at a local shop..seent that happen....my wife sold hers some years ago, when she was "cleaning out ( thinning the herd) but hers were .22s, not Blackhawks..........and the ones she kept, that have the 'military release papers, and bought overseas, from the 'PX" ,were NOT 'foreign proofed'.....she only kept them because they were 'consecutive numbered to ones found here in the state.....
