Wiping my lugers

[runscott]

Very interesting stuff - I assumed all of my blued guns were blued using the rust method. I had a 1920's S&W .44 which had a silvery sheen to its consistently-worn blueing, but I believe it's just due to heavy use over the years. From memory, it looked very similar to my 1918 Erfurt Luger and had about the same amount of wear.
