Rotating back mount for Linhof Baby Technika (Super Technika 2x3 / 6x9) models III and IV, Linhof Technika 70, Technika Press 70 and any other I might have forgotten.
6x9 hole, springed ball "bearings" to lock into 90 degree stops.
(ignore the non-square/non-6x9 mount in the pictures, as that print is for another project)
