I wonder if the gun of smithrjd is an OMS that has been re-barreled with an OMT barrel? 1950 is REALLY late for an OMT. Perhaps the gun was a parts cleanup, but I have not seen one that late. A picture of the rear and front sights and crane retention screw style would help identify the gun more accurately. A letter with the build and ship dates would be very desirable for this gun, assuming it is indeed a true OMT. Does the gun have plastic service stocks?
