Nearby SNs have lettered as shipping in October 1944. Early Navy revolvers were stamped as U. S. Navy property, but that stopped at about SN V 267000. After that, the "U. S. Property" stamp on the topstrap was used, the same as all other military Victories. Yours is in very nice condition, and the leather is a real bonus. A great prize and a valuable family heirloom.

By the way, one of the major purposes of issuing these revolvers to Navy flight crews was for signaling, using tracer bullets.
