NOS Parts Source for Compound Shutters? Or used?

Does anyone know of a source for NOS parts for this important shutter / lens. It was dropped some time in it's life and obviously landed on the setting dial, breaking off the attachment screw, still in the bent front cover. I need the screw with it's associated spring washer, plus the dial and the pieces that hide under the dial that cause the speeds. Plus it's also missing the piston cylinder cap on one end. It is a Size 5 Compound although these parts are I think interchangeable at least down to size 3. Anyone to help?

Looking for helpful answers, not, go to ebay and buy another one.

For future reference, Laflex Camera in La Jolla California has a large stock of new old stock parts for Compound but nothing is organized or labeled with catalog numbers so they need to have your old shutter to try to match from their stocks. Thanks to Karl French.
