I have an N-frame 44 Special 1950 target model # 1439xx rec'd in August 1955, so it is obvious (from sopme posts above) that some of the 1955 .45 target models with lower serial numbers were shipped later.

I am curious if frames were numbered (and placed in storage) BEFORE installation of barrels & cylinders, or if serials were applied only AFTER a gun had been completely assembled. Anyone know?
