A big 4 tube camera by
any standards, it used a 4.5 inch Image orthicon tube for the luminance
and 3 x 1 inch vidicons for the three colours. The three vidicons are
parallel, one above the other on the right hand side of the camera and
the I.O. tube down the other side. The lens is recessed into the camera
body and the tubes faced towards the rear of the camera with the light
splitter mirror assembly at the rear of the camera.
