Until a few years ago, there was a fellow named J. Korzinek ( I believe John, but he always used the initial)in PA who "blued" stainless steel. He advertised for years in Rifle magazine (is that still around?)and his ads stressed 2 things: bluing stainless steel and .22 rimfire conversions on Ruger #1's. In the late 80's, I made a project of restocking a Ruger Red Label with crotch balck walnut. I put a round knob on the pistol grip and a schanble on the forend, had J. Korzinek blue it and called it my "Black Label." Pretty neat at the time. I sold it to a friend and it's in WI so I can't post a photo. But the action was very attractive. It was a satin matte black and I believe Mr. Korzinek told me that it was the only option; apparently a the process precludes a high polish in the finish. So I had him put a matte reblue on the barrels to match. It seemed to be "dimensionless" like any blue, i.e. it was not a thick layer of anything, and it wore well in the short time I owned it.
I already had a .22LR #1 at the time, so I never hired Mr. Korzinek for one. But 15 yrs later, my rimfire #1 was also gone and I got a hankering for one in .17HMR. That's when I went looking for Mr. Korzinek and concluded he had retired. BTW, I couldn't seem to find anybody doing those rimfire conversions anymore.
