I just picked up a 65mm Super Angulon in a Compur Rapid shutter. It's not quite as described (shutter speeds are way off), but at the same time I got a fairly good deal, and the glass looks great, so I debate whether it's worth it to take this up with the seller. The problem is this: I cannot get the T or B settings to function. If I'm right, this would be a dealbreaker, because I'm often shooting long exposures. Here's what happens: If I move the shutter dial to T or B, I can't cock the shutter. If I cock the shutter first, I cannot move the dial to T or B. Am I doing something incorrectly? None of my other Compur shutters, but this could still be a feature of this shutter than I'm not aware of.
