I found a front and rear element set of a 1920s-30s Voigtlander Tele-Dynar and would like to use it with my 9 x 12 Avus when I'm shooting on 120 film at 6 x 9. I assume this was stripped out of a Bergeil 6,5 x 9 set up? The dimensions are:
Rear element 26mm (threads od)
Front element 29mm
So, I need a shutter I can mount on the Avus that would hold this set.
Anybody have a clue? Ideas?
