As described in the Plaubel PL69 post the original version of the camera offers tilt and swing movements of the back standard and shift and rise of the front standard. After I could purchase for a reasonable price by auction a second PL69 camera I had enough (spare-) parts to start modifying and extending the instrument. The two-way hinge from the back standard of camera 2 was attached to the front standard of camera 1, so adding swing and tilt movements to the front standard. The guide rail from the front standard of camera 2 was then attached to the back standard of camera 1. A small aluminum block had to be added in addition, to compensate for the increased height of the lens axis due to the added hinge at the front.
Actually for swing and tilt I prefer now to use first the front standard as much as possible and for shift I often use the back standard. So the combination of the parts from the two cameras allows now all conceivable movements with the exception of a rise of the back standard.
