85A2/ 0G3/ CV449/ SR53 British Tungsram Voltage Ref Valve NOS/ NIB.

This is an unused valve made by Tungsram at the British Tungsram Radio Works Ltd., in Tottenham, London.

It is New Old Stock, as I hope the pictures show.  It is also untested, and there is no heater on this valve to test.

This will be carefully packed for postage.

Thank you for looking.
