I didn't give that much, but it's a box full of things. One 35mm camera, this, and two old video cams. What's it worth? If it's only for Leica or even RF, I don't need it. I shoot mostly MF (Hasselblad, ect...) and have a Canon setup for 35mm. I will probably list it here when I get it.
Looks like you have a Leica M bellows. Of course the basic fittings (body and lens) are for the M mount, however if you wanted a machinist could make or modify adapters to suit. Additionally there is a focus stage and you have the fibre suitcase too I think. Does it contain the dedicated camera the MD?
If it's complete it's quite a collection! Naturally the value depends on the completeness of the set and the condition.
what you have there is a late 1950's "close-up kit" for Leica. This kit originally sold with a Visoflex I, double cable release, Bellows I (there were two bellows extensions), PEGOO magnifier, KGOON ball head, a 9cm extension tube, and a Leica M3. The case was called UYOOQ. A complete kit is rare. The reflex housing was vastly improved in subsequent years and doesn't command a decent price maybe $50-$75 with magnifier, the bellows if both halves are present may fetch $100, ball head about $70, double cable release, $30. The empty case about $70. The M3 if present about $700 if in excellent condition.
