to the tranmission unit is an air compressor. On each end the
transmission are attached the large sterring brake drums. Each
drum contains two brake shoes the adjustment holes for which can
be clearly seen.
three prongs that can be seen projecting forwards on the top of
the unit are the linkages for the selector rods which would have
been routed through the bracked mounded below. Obsured by the
frontal support blocks is a pully wheel from which the turret
drive generator was driven.
