Pye Mk5 Television Camera Viewfinder Periscope Hood

One of the disadvantages of a camera with a fixed viewfinder, like the Pye Mk4 5 & 6, was the high or low angle shots. The periscope viewfinder hood was the solution put forward. It had two mirrors and the visor could be moved up and down at will.

This example is missing the rubber mask around the visor.
