I'd love to find a dead-and-otherwise-useless Supermatic shutter with the correct aperture faceplate for the Kodak 105mm f/3.7 Ektar (so-called Heliar clone). Cosmetic condition is not critical, as long as the aperture scale is legible. Failing that, could anyone loan me said shutter so I can re-mark the one I've got (from a 127/4.7)? I'd be happy to pay reasonable postage in both directions.

Yes, I could probably estimate well enough by using the existing scale and closing down about a stop, but having the correct markings reduces the amount of brainpower required "in the heat of the moment".
