Do the the Sinar 'shutterless' mounted lenses have the same shutter mount
size, or are their lens threads modified for the Sinar mount? If it varies,
I'm particularly interested in the 121mm F8 Super Angulon. (The threads
appears to be 30mm OD on my crude caliper.)

Any recommended dealers for Copal shutters? Steve Grimes, Inc hasn't got
back to me yet.

Copal shutters are sold in the U.S. by RTS. They are the company that
sells them to camera stores and repair service companies. Any camera
store or service center can order a Copal shutter for you.

However they will come with blank aperture scales. Any camera repair man
can calibrate and mark/engrave the aperture scales for you.

I am hoping I can calibrate it myself. I don't need fancy engraving, just
marks.
