Hello all, As part of the purchase of a mint condition Beseler 23CII enlarger, the camera shop own threw in a "project" grade Beseler Dual Dichroic head. I'm supposed to have a manual on the way, which is good, because I can't quite see how this thing attaches. According to the shop owner, it can be used both with or without condensers. Interesting. Has anybody had any experience with this thing? Any opinions? I don't want to waste a bunch of time on it. Besides, it's godawful heavy.
