40mm diameter Componon lens.

[F994]

Hello guys.

A friend of mine has a Durst Componon 105 with a strange 40x1 screw mount, maybe made for some Agfa or Leitz enlarger.

Do you know if threre is any adapting ring to step it down to 39x1 standard mount?

You would be more likely to be able to step it up to a 42mm or 50mm thread.

Does it come apart? For example, all three of these Schneider Componon lenses (picture #1) can have their DURST mount removed to reveal some threads that can be used for a conventional mounting with a retaining ring (picture #2).
