camera. The lensboard carriage base plate (9, fig. 1-5)
provides support for the lensboard assembly and travels
horizontally on the camera rail (8) within a limited area. The
base plate is driven by an induction-start, induction-run
reversible motor controlled by a switch (14) on the back
support plate. A handwheel (7) provides fine focusing
adjustment for the lensboard assembly.
