What shutter is it in? name will be on the shutter itself, not the lens barrels.
Not all shutters have a press to focus feature.
Open on T, focus, close shutter and set speed.
B 0nly, lock shutter open with a locking shutter release cable.
Shutter is a Seikosha-S that goes to 1/500th (Copal 0, I think) and has B, but no T. I locked it open on B like you said. Thanks for the info.
