I took the retard cyl off and cleaned with some solvent and it did NOT change how it timed, so something else internally is not as it should be I suppose. Speeds are all too fast. By 1/5th on the dial it's pretty much snapping as fast as it goes. Probably 1/60th or so. B and T DO work properly. I see one good cleaning sleak on the back element. SO price dropped to $100 + shipping if anyone wants to play with a nice old lens!
