I don't know of a Copal shutter s/n database. But earlier ones have a chrome
setting ring- by the mid-80s they were all-black. I don't think that there were
any other changes in the design. The tiny headless locator screw should be
available from SK Grimes or anther repair shop. Although I do believe in 'doing
things right', I'll admit to using one of my LF lenses with gaffer tape on the
back of the lens board to keep the lens from twisting. Someday I'll get it
properly mounted...Mark Sampson

I get that I need the wrench for the best fit, but would such a wrench still be
available for a camera that's been out of production this long. Granted the
Copal 1 shutter might have been used later, but can't imagine they are a dime a
dozen these days. Well it turns out there are a couple of types on Amazon, one
for DLSRs and the one for large format are specifically labeled copal 0 1 and
3. It might solve the problem. Looks like a card more than a wrench.
I did find a serial number on the copal 1, but no screw. I did find a tiny
hole that was covered by the retaining ring/jam nut that might be threaded. As
many of you suspected this probably was the set screw that others have talked
about, and thought was most likely gone. It is, and at that size a replacement
would probably be the infamous wish upon a star. Even if I found the screw,
unless it was a very tiny screw with a very large head, it would have to be put
through the lens board itself
The serial number is in the 7300 range, but found no reference to how old it
might be like one can often do with some cameras.
The process continues.

Mark, get the tool. If the retaining ring has a collar that fits through
the lens board make sure that it is not thicker than the metal board or
if never will tighten (just sand off some of the collar's thickness if
it is too thick. ) Another way to tighten the lens to the board is to
align the shutter before where you want it to end up (like 10 o'clock
instead of noon) and then tighten the retaining ring (the nut) and when
it is as tight as you can easily make it (assuming you don't have the
proper wrench - get the wrench!) hold the ring in place on the back side
and screw in the shutter to its final position on the other. It just has
to be snug enough so that it won't rotate when you cock the shutter.
