Tyne page 431: "S&H's earliest developments were based on the results attained with some special double-grid tubes which had been evolved during WW1. The triode V27 was the progenitor of the tubes developed for telephone use in the postwar era." ...
"In the line of tetrodes for repeater applications the R was the first type, designed for the new multiplex telegraphy system. The R-Type was soon superceded by the OR. Main difference is that the OR has a oxyde coated cathode."
