These lenses only existed in one-pin version, and they have a finish quite similar to the first Zeiss lenses.
Some of the Zeiss lenses were sold under the Voigtländer name to go with the VSL range. Some of these lenses had begun their career as Contarex lenses, and most of the range was to be recycled as Yashica / Contax lenses. The lenses produced in that mount were mostly from Carl Zeiss and were of high quality.
