Yes, interesting gun!
If there's no ordnance bomb on the butt, I'm betting it'll letter as a USN Roslyn, Virginia Victory... shipped in December of 1943. I think there's at least two December 1943 Roslyn shipments, December 21, 1943 and December 30, 1943.
I've got two .38 Special Victory models with the same markings and they both lettered to the USN Roslyn, Va.
One has a post war German stamping on the backstrap and the other does not. Both shipped December 21, 1943.
The 1903 Colts that had Roslyn destinations were designated OSS shipments.
