the 1911 is the Colt wwI reproduction. Case hardening done by ( or for) colt. The USFA is done by Turnbull. Colt colllectors tell me that the 1911 repro, which appears darker under different lighting is a fairly accurate rendering bu that the brush/polish pattern is not the same as original pre 1920 1911s. In any case, it is pretty enough for me and, by virtue of an optimum out of the box trigger, shoots right along with a couple of custom 1911s I use.
