The Baird Televisor was made by Plessey in England from 1930 through the early 30s. It was the first television receiver sold to the public. About 1000 of these sets were made and sold for about 26 British Pounds, which, at the time, was a considerable amount of money. When buying a Televisor, the purchaser signed a contract, which described the programming available. The Televisor was also available in kit form. This is serial number 717.
