It's like the old saying, "There are no stupid questions". No, I didn't have the shutter cocked, or, rather, I had it cocked just once several days ago, when the lever opened the shutter correctly. After that one time, I have been working the lever without success. No success, because the shutter was not cocked.

Now, if I cock the shutter, the lever does what is expected.

Weird. Or, perhaps, not so weird. I have, after all, only handled a very limited number of LF lenses – maybe three – before this. None of them exhibited this behavior. But they weren't Seikos...

In any case, case closed. Thank you very much!
