Tiny Copal 3 Retaining ring

[Ginette]

I look around for a Retainer ring for a Copal 3 instead of a Mounting Flange. I wish to use a lens board adapter and the large flange is too large.
Can I found one on the market or need to be a custom made?

You could try S.K.Grimes:

They have both flanges and retaining rings.

If you mean that you need a jam nut for a Copal 3 you could order it from any Rodenstock lens dealer. That is what Rodenstock supplies to mount the Copal 3 shutters that they sell. The mounting flange is an optional accessory. The jam nut for the Copal 3 also includes a stand-off ring that goes over the threads before the jam nut is tightened.

Thanks Mr Salomon, I will look through Rodenstock dealers in Canada.
If someone have one not in use, just PM me.
