I have purchased a rather worn out specimin, or should I say much loved. I have a number of lenses that belonged to copy cameras-repromasters and it would be nice to use the back shutter. I have gone as far as having barrel mounts made so that the telephoto can be used at normal extention. can anybody suggest a way of testing or repair or service, happy to telephone

Amosp,
I have instructions on adjusting tension for the focal plane shutter and it will set the speeds very close, would be happy to send them to you! Email me at
