  • Bemerkung

  • Official GPO Registration No. 249 crystal receiver approved by the Postmaster-General (P.M.G.) and the B.B.C., manufactured by City Battery & Wireless Co. starting in winter 1922.

    This variant represents the shorter cabinet version constructed without the side-mounted headphone compartment/receptacle found on the expanded cabinet version.

    The receiver features a finely wound inductance tube with 20 tappings, a "Detector De Luxe" with micrometer screw adjustment, and twin crystals (an open galena/cat's whisker detector combined with a Perikon detector) mounted on a superfine ebonite panel. All internal connections are fully soldered and insulated. It is housed in a compact mahogany cabinet with a hinged lid housing the operating instructions.

    Lineage & Cabinet Variant Note:

    As documented in Radio Radio (Jonathan Hill, p. 68, fig. 75), sets bearing GPO Reg. No. 249 originated with City Battery & Wireless Co. in late 1922. The model was produced in two distinct cabinet styles:

    • Standard Cabinet: Includes an integrated side compartment/receptacle for headphone storage (Width: 8.5 inches / 216 mm).
    • Short Cabinet: A more compact cabinet omitting the side headphone compartment.

    Both variants were also marketed and distributed through London selling agents Fowler & Brigden (130 Euston Road).
