content: A 4-pin brass base (short pins) with plastic insulator, vertical collector assembly, tipped G-shaped envelope. Shaw "S" molded on base insulator. No extant maker's markings. Appears very similar to the British type R made by Moorhead, although the envelope is slightly larger and both filament connections enter the cylinder from below.
