Summary
Two lens mount adapters. Each adapter mounts a screw threaded lens to a bayonet mount. They are metal with a brass in-lay. The front is marked 'Voightlander Japan'. One has '50 75' whilst the other has '28 90'. The significance of these numbers is not clear. Each mount has a pait of plastic covers, black over the bayonet and white over the screw aperture. Since 1999, Voigtlander products have been manufactured by Cosina, Japan.
