Thanks Expresso Wizard!
Yep it's fun to collect (like hunting for buried treasure) and lots more fun to use.
My favorite camera for sure, Geoff Berliner feels the same way. I do have some newly developed roll film to print and put up here soon. The short-mounted 180mm F2.8 CZJ Zebra Sonnar is so beautiful to look through and shoot. BTW that was the whole reason I got into the Pentacon Six mount lenses.
PN341 210MM MAKI CLEAN NEW INDUSTAR 210 4.5 by

I decided to keep the rare Plaubel PN/341 Makiflex Lens Board, but I was unhappy with the 210mm F4.5 Industar-4 lens, it had some fungus, and I couldn't get it open to clean. So with some persuasion from Dremel Cutter, I was able to break it free from it's glued-in mount. I cleaned the board with ammonia, then set it directly in the sun, and baked it for four or so days. Now the fungus odor is gone, it's good to go for me. I threw the Industar in the trash, the fungus inside really bothered me. So now I went looking for a replacement, I found this more modern MC Industar 210mm F4.5 new in box with flange, so I bought it. It's now well on it's way from the Ukraine. I used to have quite an assortment of Russian P6 lenses, back when I was interested in Kievs,Pentacon 6/Exakta 66's, Hartbleis, etc. I redid the light traps on the new board, it's ready to accept the new Industar.
