Do Synchro-Compur shutters come in sizes that correspond to Copal sizes? And if so, are they identical from one shutter to the other? Thanks.

Yes, the sizes are the same. There is one addition, Synchro Compur shutters were also available in size 00 (smaller than the size 0), which Copal didn't produce.
Thanks, Bob.

Also note, there was an illusive #2 compur. Very useful, very hard to find. I've got an old 14 inch Red Dot Artar mounted in a compur #2. The lens can't fit in a #1, but a #3 is serious overkill. The #2 is way smaller and lighter than a #3. And no, my 14" Artar is not for sale!
I actually sent a query to Copal Japan asking if they ever made a #2, and the answer was no. So, the various #2 sizes (they aren't all the same, but they are all #2 - go figure) join the #00 as sizes beyond the Copal shutter line.

Just a little note: The harmonization of shutter diametres, threads & spacing have not allways existed . You will see that older (-60 and before) Synchro Compurs have slightly different (incompatible) threads than Copal & modern compurs & prontors. I experienced that when trying to remount a newer Komura 210mm (for # 1 shutter) lens-cells in an old Compur shutter. I don't know when the standardization were complete. Thus: measure both spacing & thread diametre/travel when preparing to remount older shutters/lenses.
Another footnote. In the Compur #00 the sizes of the threads of the Synchro Compur #00 is slightly different from the earlier Compur Rapid and pre-war Compur #00.
sorry for resurrect the thread, but the link provided by Bruce seems has been moved to

Just if it's of interest of someone.
