Hi all, I've been offered to buy a Focomat 1c. Although no spring chicken, it seems to be in good shape with mechanical parts moving smoothly. It has not been used for a few years. Assume that quite a few of you have hands-on experience with this enlarger. What in your opinions is good about it, and what is bad? Anything in particular to look out for - known production weaknesses, that sort of thing? There's no filter tray. What is the usual workaround for this, provided I don't want to stick the filter between the lens and the paper. I appreciate your insights on this - Thanks!
