Hello I bought a Schneider Symmar S MC 240 f 5,6 and I need a spacer, retaining ring and a lens board for Copal 3 ( Chamonix F2N and Linhof Technika V ).
There are difference between Copal 3 and Copal 3S ?
I've found this on ebay but says Copla3s, ( Small Shutters ) , so I don't want to buy womething that I have to send back...

Thank you!

Copal 3S is just a bit smaller than a Copal 3. The lens board shouldn’t be a problem, but anything with threads will not work. You can look up the size differences somewhere like the SK Grimes site and look for “Shutters” for all of the dimensions for many different kinds of shutters.
