You mention that some of the revolvers sent to the US Maritime Comm. were through the DSC. My factory letter states my Victory # V 486897 was part of a 100 gun shipment directly from S&W, Jan.3rd, 1944, to the US Maritime Commission @$20.60 each. No mention of the DSC. After the war, the revolver was sold to the Boston, MA Police Dept. and so marked on the grip frame B.P.D. 445-V.
Right on the butt near the V is a very tiny flaming bomb stamp. There are no USMC markings on the revolver. It also has the military Black Magic finish. Mr. Don Mundell prepared the letter.
Thanks for the great post. Big Larry
