Yes, ye brother of the godforsaken, there is a website, it's in Dutch, I don't know if it babelfishes. It's called http://www.marktplaats.nl -> go to the section 'foto/toestellen/dia' and then onwards to the section 'diaprojectoren'. FeeBay bought this website last year, so there are some improvements made over the original design, but it's still incredibly primitive compared to its new mommy. Some people post images, some don't. Type in the zoek = search field of the diaprojectorensection 6x6 or Liesegang, Noris or Kindermann and up they come.

If you're unsuccesful, send me a pm. I'll help you from there on.
