I have one of the Colt Officers Model Target in 32, serial # 640608 which Colt says was shipped in 1939 so they must be with the 38 OM too.
So the 22's were a separate serial numbering than the 32's and 38's. Got it.
You just can't beat the quality and workmanship on those pre war guns.
Let us know how she shoots Toyman.
