  Lack of parallelism could possibly be due to the focusing cams having
dried out grease or misadadjusted cam followers. They should be lubed with
fairly heavy grease. 
  Feel the focusing panel as you focus. It should not have any see-saw
action as its moved. 
  The absolute parallelism is achieved with shims between the ends of the
focus rack and the lens board. It can be measured using a plate of glass
lying on the rim of the lens. It should be absolutely parallel to the back
of the camera. Once established this won't change. 
  the front trim panel is separately shimmed and may not be quite parallel
to the camera front even when the lens board or carrier is. Shims are easy
to lose and someone in the past who disassembled the camera may have lost
one or more.
