Help identifying this lens mount
Popped in to my dealer today, before selling me a Rolleiflex 2.8F, he brought out this Angenieux 9.5-57mm 16mm cine zoom. He knows I want to convert something interesting to use with mirrorless. He has no idea what it is or worth, and is selling it for a customer who inherited it and equally has not a clue.
I thought I'd be able to work out the mount pretty quickly, but the three flange is absolutely baffling - any ideas welcome! The third photo shows it was used in Swedish Radio (a lens for Radio umm)
Film amateur with a few rangefinders - Leica III, M2/M3, Werra 3 and Zeiss Super Ikonta 534/16 medium format.
Apart from that have a Rolleiflex 3.5F, the odd Minolta XD7, Hasselblad 500cm, a Topcon Super D and an Intrepid 5x4 large format (not the half of it but I am clearing them out, honest).
I do all my own black and white developing at home.
