Not quite in the same league as Sassans exotics
but we went to a camera fair a couple of weks ago and saw some very interesting kit. I was looking for info on a real odd ball, the Zeiss-Ikon Cantarex when I found this site. It is mostly in German but there are some good pics of cameras from Voigtländer, Leica, Rollei, Pentax, Canon, Nikon and a few more. Links to each on the left pane.

Same site but in English is the Early History of Single Lens Reflex with example pics of the cameras.
