I have an older 305 G-Claron. It's currently in a Universal No. 3 shutter but, I think the shutter is way too slow. I'm considering getting it CLA's (Aside from Flutot's, where else do you get your shutter's cleaned?) or replacing it with a different kind.

It doesn't fit in a Copal 1 like some of the newer lenses. With that, what other shutter types work with these older lenses? Does the fact that it is of Dagor design matter?

thanx in advance,

Joe P.
