Not too long ago, I acquired a Graflex 8x10 Focal Plane shutter in good working condition. I don't know how old it is, but Graflex FPS were first patented in 1902 as it says on the plate, my guess is that mine had been completely overhauled some time in the past as the curtains appear to be in good condition, springs are good and strong, and speeds seem to be fairly accurate. I'm attempting to build an 8x10 SLR around this shutter based on the Graflex Series D/Super D, and was wondering if anybody here has a technical/repair manual, showing sections, cutaways, details of the Series D/Super D? I couldn't seem to find it on graflex.org and I don't really want to disassemble my Super D to see, particularly regarding the mirror mechanism and the synchronized shutter release. I can't do without the auto-diaphragm feature of the Super D. Thanks in advance.
