I have an old Planar 80 lens of the C variety that has pristine glass and was CLA'd recently. The only annoying thing is the d*rn painted numbers that seem too easy to mar and scratch - would it be possible to repaint them or make some kind of label or new engraving?
I found the answer I was looking for yesterday, but I wasn't able to delete this post. Basically, in involves making a set of numbers with decals or else replacing the whole shutter speed band, as the numbers aren't engraved, only painted on.
