This is the Marconiphone Model V2A (‘Long Range Model’) manufactured in 1923 by Marconi’s Wireless Telegraphy Co, Ltd. (chassis manufactured by Plessey, Holloway, London). The instrument is housed in a polished mahogany cabinet bearing the ‘BBC/PMG’ stamp and GPO Registration No. 0175. A contemporary advertisement for a similar model, the V2, is reproduced below. The price of £24, complete, was a considerable sum of money in 1923 and included £1 15s royalty paid to the BBC and 12s 6d per valve royalty paid to the Marconi company.
