I've got a voigtlander R3m, and I wear glasses.
The rubber sleeve protecting the viewfinder is starting to tear. And once it is gone, it will be open season for my glasses. (I can't see without them).
I need a solution nto repair the rubber before it is too late.
I know an older Nikon SLR (I believe the Nikon FM3A) viewfinder will also fit; but i can't find one in my local stores (I live in Hong Kong, so there are a variety of SLR accessories that can be picked up cheaply; but nothing that will help my rangefinder problem).
I appreciate your help.
