My father owns a very old Voigtlander Vito camera and now he would like to sell it (unused since I was a child). Of course there's eBay, but I'd like to know whether there are specialised sites (similart to mpb.com for new gear). The point is that while I can evaluate the condition of a vintage lens, I've really no clue for a camera. It looks excellent outside, every mechanical part seems to work as expected, there's just some fog in the newfinder, but of course without shooting some film and developing it I can't tell for sure that it works. Sites as mpb.com do the final evaluation and quote and if the thing doesn't work they send it back to you.
If you know something, please let me know.
