For curiousity, I asked Skinners in the very beginning of the auction whether the Kwanon-D has a written expertise. At this stage, it was very clear for me that the final price would be in the range of at least 100,000 USD. I expected that it would be much higher, maybe 300,000. When you collect paintings, you expect an expertise for each painting for more than, say 2,000 USD. As you all know, cameras, i.e. Leica screw mount types are as easy to fake as paintings, or even easier.
I received a very short answer: No expertise at all, but they have shown the pictures to Peter Dechert and he has valuated its real from the pictures.
BTW, I recently got the auction catalogue of a Vienna auction house and they announced a "Skinner" Canon, starting price 3,000, expected price 5,000 -6,000. They write: "Also included: documentation relating to this camera including rare literature and the original letter of authenticity from Dr. Peter Dechert". Fine that!
This is why I said Skinners marketing behavior in case of the Kwanon-D could be called stupid. It could be called something else as well if the camera ever turns out to be not legit. My suggestion: If it will ever come to the light of public, it may be authentic. If not, it was probably a fake, excellently made to fit 100% to a picture published in Peter's book...
This said, I'm still hoping the camera is real, for sake of CANON... otherwise I wouldn't have shown the picture on my private virtual museum...
