'Colortel' mechanical colour adaptor, to fit onto the front of the monochrome television set to convert NTSC-compatible monchrome set to colour using a field sequential disc. Made by Color Converter Inc, Indiana, United States, c. 1955. Part of the Donald Fleming Collection of North American television receivers. Accompanying converter chassis is missing. An associated 14 inch RCA Radiotron cathode ray tube is believed to have been included to swap out with the standard and brighter 24 inch tube in the monochrome television to prevent screen burn when using the ‘Colortel,’ which focussed the bright and colourful images on a small section of the screen. Col-R-Tel mechanical colour convertor and RCA Cathode Ray Tube circa 1955
