Decca 1000 Projection Set
(click on pictures for high resolution images)
This is a postwar (around 1949) British projection set. This receiver produced a 4ft X 3ft picture on a silver painted screen that hung from the picture rail of the living room. (The picture rail in older British houses consisted of a moulded wood decorative strip about 3" X 1" mounted about 18" from the ceiling all around the walls. Metal hooks that fitted the profile of the moulding allowed pictures, mirrors and the Decca projection screen to hang without banging nails in the walls. A similar rail was fixed about 3ft from the floor to prevent chairs from damaging the wallpaper. This was called a ' DADO ' rail. Here is a newspaper ad from 1953.
