I visited Henry's site this evening, having just purchased a "beater" IIIa BD / f2 Sonnar 50.
After spending nearly 2 hours browsing Henry's site and reading about his background and detailed info on Contax and his approach to servicing them, I am confident that his work is "the best".
Over twenty-five years ago, my Retina IIIc needed service, and my father asked his friends who worked in the US Senate photo lab if they knew of anyone who could work on my camera; they referred us to a retired gentleman in suburban DC who all the DC photogs sent their mechanical cameras to... he was a retired Navy machinist who started servicing cameras during WW II; he was very methodical and very particular. I wish I could remember his name... he was in his 70's back then, I think.
At any rate, I think my DC camera guy and Mr. Scherer are cut from the same cloth: very high-quality.
Just reading Scherer's article on shutter-tapes for the Contax is enough to boggle my little mind...
Once my ugly IIIa arrives, and I get a good look at it, I'm sure I'll be signing-on to Henry's waiting list...
