Good Afternoon, Mark,
Assuming that its functioning is as good as its appearance, I don't think you got taken, especially considering that you also got the 35mm adapter. It is possible that you might come across one at a slightly better price, but it sounds like a good deal to me. The Super Ricohflex is what I used in the late '50's when I was shooting for my high school yearbook, and I still have mine (no 35mm adapter though). I really should get it out and use it; I know that it can produce very acceptable results. You just have to get used to the separate film advance/shutter cocking.
