open and close the shutter to facilitate focusing.
c. Lens board. The lens board is provided to permit mounting the lens
assembly in the front frame of the camera. The front vertical movement

the entire surface of the easel. One end of the 20foot POWER CORD is
permanently attached to the converter. When set up for operation, the
converter is secured to the rear of the cabinet by means of two converter
incandescent lamps (four 150watt incandescent lamps in each assembly). The
light assemblies are supported by a carriage assembly (two support arms)
that are secured to the front end block. Each light assembly has its own
