'Bowjection' projection television by Rainbow Radio serial no X10013, 1952. Monochrome video projector using the Mullard optical system (2.5 inch tube in a schmidt folded optical system).
A Rainbow Bowjection projection television receiver, made in England around 1951.
Projection television sets were popular in the early 1950s, although they had been around before the war. Instead of using a very expensive large cathode ray tube to give a big picture, these sets used a 2 inch high brightness tube to project the image on to a screen (4 foot x 3 foot).
The Bowjection was made by the Rainbow Radio Manufacturing Company, Mincing Lane, Blackburn, Lancashire. First announced in May 1952 and advertised in October 1952 at £175 plus an extra £21 for the special screen, advertisements continued regularly for several years.
