Even the amount of sandblasting done prior to finish can substantially change the color of the finish.Īlso, many slide and frame combos will appear the exact same color at one angle, but may look different at other angles. I'm confident they probably didn't use three different finishes, and that the change in shade is due to surface preparation being different. There are at least three shades of finish on their pistols in 1945 alone. Remington Rand's color got lighter all during 1945.

The same finish can be applied and look somewhat different on surfaces prepared in slightly different methods. The way the surfaces were prepared for finish played a major role in what the finish would actually look like. I believe there were some cases where slides and frames were manufactured at different times over a period of time when manufacturing processes and/or finishes changed slightly, which led to slightly mismatched finishes in some cases. Some late 1944-early 1945 Colt pistols have slides that appear darker and smoother than frames. Some very late 1945 Ithaca pistols have darker slides than frames.

Remington Rand pistols in some serial ranges often are slightly mismatched in color. There are some slight differences in some cases. That said, there are exceptions to the rule. "The receiver and slide must always be the same color (shade, sheen, etc.) whether blued or parkerized." 103 in Clawson's Collector's Guide dealing with original finish:
