Early Zoom Lens: Part 3

This is the Watson 5×1 zoom made by Watson and Son, near London. This lens debuted in 1948 and is mounted on a Marconi Mark II at the 1954 Empire Games. The zoom command would be on the other side of the camera, but notice (1) the metal cabled focus demand wheel near the operators hand and (2) the early Vinten Mark I pan head.
