Additional Information provided by Jim Kubajak:
"Interchangeable lenses in Topcon UV mount from 28-200mm. UV mount lenses also for Topcon Uni, Unirex and Auto 100 cameras. This is probably the only lens mount ever shared by a focal-plane shutter and a behind the lens sector shutter. These lenses are good, but watch out for sticky auto diaphragms, they are expensive to repair."
