Have acquired a Dagor Series III 9-1/2" in Compound on ebay. It has a number of issues:
1. Diaphragm is stiff but usable. Does it hurt anything to work it when it is stiff?
2. Strange cable release socket...it is unthreaded, and has a locking screw. The screw is bent. Any ideas on finding a replacement screw, and a suitable cable release?
3. The aperture scale markings are 2.9 4 8 16 32 64 128. Obviously this lens did not come in this shutter originally! However, what is the likelihood that the spacing is correct? I have ordered a lensboard, but don't yet have a way of looking at image on gg or taking a test photo.
4. Shutter has a few usable speeds: 100=instantaneous (will measure, sounds like 1/50); 50=1/4; 25=1.5; slower speeds verrry slow and erratic; B OK; T requires MBT lever to be moved away from T to close shutter. Can use it as is, will get a CLA if lens is a good performer.
Lens is marked "GOERZ DAGOR F: 6.8 SERIES III No 4 FOCUS 9 1/2 IN. No 310277". Approximately where would it fit into the Dagor history?
