Lens mount to Copal No. 1

[JimboWalker]

Just curious. Are there lenses that you can "plug and play" into a Copal No. 1 shutter?

[Bob Salomon]

Yes, but that shutter may not have the correct aperture scale
3 lenses that will screw directly in are the 90mm 4.5 Grandagon lenses, 180 and 210 Sironar MC, and later.

You might also need a shim or shins for optimal results.
