WESTERN ELECTRIC WECO VALVE, 1921

Made in Britain from the American version with a British 4 pin base.
Also made by B.T.H.Co. and called the Weco Valve. Mullard also produced this valve. Ideal for battery equipment with a nominal 1Volt quarter amp heater, and only 17-45 volts anode.

Introduced by the Western Electric Company in 1919 and developed originally by Hendrik Johannes Van der Bijl as the 215A

Your comments:

• I was very fortunate to get one of these for my collection some years ago, It's my earliest and most valued valve. It has a standard 4 pin base as shown in your photo and could fit my Polar Twin receiver that recommends using Weco valves.
