I recently bought a one-owner M3 DS with a DR Summicron from an estate in Chicago. The camera and kit are absolutely lovely. The only issue is that the vulcanite was flaking off with every time it was handled. I finished peeling it all off, mostly with my fingernail, and cleaned the remaining adhesive off the body with acetone. I ordered a dark blue leather replacement cover from Morgan at cameraleather.com. He was responsive and helpful and I had the new leather in my hands in about five days from the date of order. Exceptional service! And the leather... oh my... it's gorgeous. Total install time was about ten minutes, and that with me trial-fitting it and figuring out how I was going to do the install. It went perfectly. it was simple and easy. And I think it looks amazing!
My first M body was an M3 in 1974 that I promptly traded back in for an M2 that developed a severe case of fungus when I lived on Guam. Since then I've had an M4-2, M4-P a couple of M4s and another M3 or two (and an M8 and M9P.) My vision got so I couldn't focus the M4-P/M8/M9P well any more so I sold them in 2016. A conversation with a friend recently about the 1:1 finder in the M3 and the differences from the later finders got me to wondering if it was different enough that I could still use one, and much to my surprise, I can see the focusing patch quite well in the M3. It pleases me to have an M again.
