An extremely rare 1931 Royal Navy Radio HF Receiver Q7 Admiralty Pattern 7492A Made By Radio Instruments Limited (1922-1988) of 12 Hyde St.,London WC1 and 40 Purley Way, Croydon.

In pretty good cosmetic condition, this receiver is being sold as a collectible for display only; a real piece of British Admiralty Radio Communications history! It is sold with two valves, a Mullard PM1 HF and a Mazda P220.

Comprising two rheostats, for the receiving and quenching valves, and various input and output connectors.

Approximate Size (WHD): 20.4 x 23.2 x 12.5 cm  

Made from coated and uncoated non-ferrous metal and brass, this amazing piece of radio equipment has a brass label screwed to the front engraved as follows:-
