Another oddity: It's a 16" process lens (no manufacturer's name) on a 5" extension tube with a square, 4" lensboard base. It also has a long shade that screws on to the front. I think it may have been set up this way to be used on a Speed Graphic (flat lens board variety) or an RB Graphic, but I can't say. The lens is big, heavy and F8, not f9, as most of the process lenses I've seen seem to be. The aperture is a bit stiff but works fine, the glass is good, but certainly not pristine. There are no significant marks, chips, scrapes, scratches, or separation, but it has a little haze and has been cleaned a lot. It should take fine pictures, but I have not actually tried it yet. There is no other flange (this one may be separable from the tube, don't know) and it is uncoated. My guess is that, sans tube, it will cover 11 x 14, but guesses are just that, guesses. As I said, I haven't tried it. $115, shipped in US. More for you folks in other places, depending on postage. Paypal fine, no gift status necessary. Proceeds go to PHSNE, minus 3% for APUG.
