  • The " NATIONAL " SUPER CRYSTAL SET Is the ONE and ONLY that Receives BROADCAST TELEPHONY up to 110 Miles.

    In London, for instance, it will receive Birmingham Broadcast, but at this range, signals are very faint. It is ideal for use up to 50 or 60 miles, for clear reception, and is undoubtedly the most wonderful Crystal Set yet produced. Birmingham BBC Station can be heard on it at Works, Acton, distance, 105 miles.

    Price Complete Set, including Brown "F” Phones. 100ft., 7/22 aerial wire, 4 Insulators, £3/18/6.

    BBC/PMG stamp, GPO No.441.
    (matching amp.GPO No.3336).
