| Beschreibung |
Basing upon its look and on the few data printed on the label, it should be an improved version of the Marconi-Osram S625, with dull emitter for low-power battery operation. According to data on the label the Cossor S.G.210 operates at 90 volt anode voltage and just requires 2 volt at 0.1 amperes for the filament.
Probably it can be dated around 1927 or 1928, shortly later replaced by the single base version.
