Years back I got a Super Graphic with a 135 Optar (Wollensak for Graflex) in a Graphex Full Synchromatic shutter. ( This may be a renamed Wollensak shutter?) The shutter has very good speeds per a test I had done, but the resolution of the lens isn't all that great. I was wondering if I can pickup better glass and use the shutter. It appears to be what I would call a #1 shutter, but I'm sure there are differences. My needs are something in the 90 to 210mm range, and if there was better glass from that era, I'm thinking of looking for a lens with a bad shutter and using the elements. Thanks for any help you can provide.
