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!

Good pickup Havoc. The Seiko shutters need to have the shutter cocked.
In terms of the VXM lever, the shutter should have a self timer on 'V.'

Almost deleted it thinking it couldn't be that. Happy to help.

Read this next https://www.largeformatphotography.i...y-and-use.html

I should have read that way back when I joined

Some shutters break very easily if forced


but not all
Some are foolproof

Depending on the lensboard and Seiko shutter, the lens cells may, or may not, be transferrable to any other Seiko shutter.

For example the lens cells on these two 75mm Topcors can't swap shutters. (Inside vs outside lettering).

Sorry for reviving this old thread, but i was really curious if the 120mm super topcor fits inside the body of a horseman 45FA while its closed? i cant find any information on the dimension of the lens.

Cheers
