I have seen several earlier references, one by the B.A. Lafferty and another by Harry Jones, saying that even the earlier Mauser Lugers were salt or immersion blued and the higher polish on these Lugers caused collectors to believe they were rust blued because of the color. Jan Still says all these were rust blued. I dont have any pre 38, post 1923 Luger that have the original finish to look at. Any thoughts either way. If the early ones were immersion blued, most of them had the bluing removed on the internal parts of the frame and receiver. Lafferty goes on to say all the post 37 Lugers had blued muzzles (not polished white steel) which pretty much agrees with a consensus we had here at the forum after long discussions. Thor
