History:
Being one of the very first commercial televisor to be introduced in the english market in 1930, the Baird 'TELEVISOR' model may have been manufactured at around one thousand units by the Plessey company for the J.L. Baird Co.
Experimental broadcast 30 lines TV programs by the BBC have been seen on it till 1936. Although those early TV transmissions where dedicated to the english people, they also where often received in various part of France. Some archives reports receptions of Baird/BBC programs in the northern France, Paris and others, depending upon propagation conditions. Anyway, one could say that the BAIRD's TELEVISOR might have had a relatively modest success on the market, due to various factors. One of those, being the high price of the machine, which was also offered in kit packaging (without the housing), to lower the price.
Nowadays, only few units of the BAIRD TELEVISOR survived. Some units are exposed in various english (Bradford) and US (ETF) museums.
