Twinned Minolta X-370 film cameras

in the stereo-view above, the flag and truck are in the proper 3d plane.
in the stereo-view below, the  gray car is not in the proper 3d plane.
synchronization of the two cameras is achieved with the use of two shutter release cables held in a plastic jig, triggering both with
one thumb, but the synchronization can be hit or miss. With the high cost of film and processing I do not plan to use this 3d system again.
