Need a copal# 1 aperture scale for the 90mm f4.5 Rodenstock Grandagon. New, used or an 1:1 image of the aperture scale that can be reproduced on to a blank Copal Scale insert.

There is no "rule" to dictate f- number scales spacing, however, on many late model copals the f-numbers are spaced the same as the shutter speed numbers. Knowing this you could cobble together a scale like this if you can find a picture of your lens on the Internet.
