Another method to obtain the f-stop scale for a G-Claron: call the Schneider
distributor in your country and ask them how much the scale costs (or both for
the Copal 1, if you want both).  They just screw on and are probably available
as replacment parts.  But they might be expensive.  This also assumes that you
have a regular Copal 1 -- the ones with Nikon LF lenses are slighly different
in how the aperture scales attach.
