| Descripción |
Distributed and possibly manufactrured by H W Sullivan - the "Improved Pattern Valve" Inverted bowl anode and a tapered spiral grid matching the contour of the anode. Designed to overcome the patent on the tubular anoded "R" valve. Stokes - p208
It is possible that this was manufactured by "Rivers Moore" - hence the name. "Wireless Weekly (UK) June 6 1923".
