Dirk,
I have one too. I bought it with a Nikon mount and was lucky to be able to buy
a Rollei mount, I cannot remember if it was from Schneider or Rollei. I do not
know if they still have some.
I did machine a Rollei mount for it but could not work out why it would not
turn all the way to lock. I machined a little at a time to make it smaller
because I thought it was too large, but that did not work. In the end it was
too small and moved about. I then bought the proper one and realised that I had
drilled holes for all the screws but the Rollei one did not have one hole
because the stop down pin dropped into it!
