OK, I GIVE UP! I checked local metal plating and metal stripping businesses around Phoenix and after talking to half a dozen or so, picked one and took all the parts to them...now I won't be able to sleep for a week until I get them back. The old guy there knew exactly what to do, although he couldn't name the black finish on the parts. Rhuff, guess what he is going to use...Methaline Chloride, the active ingredient in Klean-Strip...but a much higher concentration...And the cost, you might ask...why yes sir...$42 includuding hazardous waste disposal!...half of what I've already spent. Now let's not jump for joy until I have them back. Pictures and comments will be forthcoming in a week to 10 days.
BTW, Patronen, I did a search on Suncorite 259 and it sounds EXACTLY like the stuff on my Luger.
If I could have found someone to do soda blasting I would have tried it. The info I found on it and the comments from the local shops sounded encouraging. I don't have compressor and it does make quite a mess. But this shop was ready to go.
So, once again, thanks to all who voiced their thoughts and suggestions and encouragement. Steve
