I bought a 75mm Super Angulon that was on this Sinar Board with the aperture adjusting cable. The Super Angulon was in a Synchro Compur shutter - I am told this board and aperture cable will also work on the 90mm Super Angulon in a Synchro Compur or Copal 0 shutter. I have no use for it and have no idea what it is worth. I will ask $40 plus shipping. If I am wildly under or over please let me know.
