I recently picked up a very nice 5x7 Seneca with one (perhaps, with your help) minor problem. The triple extension bellows are for the most part in very nice shape, but there's a 3"-4" section near the front standard where the seam at the bottom has split in the leather (or synthetic) covering and is peeling away from the lining. But, the lining underneath is light tight. What's the best way to reattach the covering?
Another question - the lens is a Wollensak Symmetrical convertible in Autax shutter. The aperture scales are in the old style - how do I correlate that to something I can meter?
