My 2 cents worth. If you think you would use it, make him an offer at a number you feel like you could get out with your skin if it didn't work out for you. There is not a huge market for old film cameras and chances are this guy is not using it and wouldn't know where or how to get rid of it. You were not out looking for an old medium format camera. Were it me, I'd probably offer somewhere in the $350 t0 $400 range. If you decide not to use it and sell it, you are going to have a few hours of your time tied up in selling it, so I would assume that when making my offer. I do buy and sell a fair amount of gear . . . I also keep and use a bunch of it. Bill Barber
