Hello, firstly I can tell this shutter has been previously messed with. Anyhow... The current problem / problems are:
When you hold the shutter in a normal dial upwards position, and cock the shutter... the blades open partly. If you set the time to 1 sec, and fire it, 1) the blades open, 2) the blades close promptly (like 1/30 sec or so), but 3) you can hear the slow speed run after the blades close!
When the shutter is laying on its back (shooting straight up), if you cock the shutter, the blades don't open partly. But when you fire the shutter the blades don't open at all. The slow speed runs despite no leaf actuation.
B and T work fine. From a basic look inside no issues jump out at me.
It seems like an issue somehow with the lever at the lower part of the shutter that 'grabs' the leaf actuation lever. Note how in the photo where the blades are partly open it has engaged, but in the other photo it hasn't. [Bottom of the shutter is on the left side of pic #1]
At 1/200 the behavior is the same (except no noise from the slow speed regulator).
Thanks for any help :-)
