| Description |
Shortpath is a Cosmos brand, see Keith R. Thrower, British Radio Valves, page 48. Probably an anglicised version of the WD11 from the USA.
According to Tyne (pp.373, 374) there are three variants:
- SP18/B
- SP18/G
- SP18/R
in the Benjamin Catalog all SP18 are tubular, although Tyne shows an SP18/G having a globe shape. Error?
The SP18 without dot or suffix (B, G, R) is definitely existing (see photo)
