Andy,

I thought that section 110 referred to items not made in this country or to a UK specification
Valves area typical example. CV509 (6V6G) is listed as being manufactured by STC (UK) and RCA (USA) and has two Air Ministry numbers, 10E/349 and 110E/90. The former meeting an MOS specification and the latter to a JAN specification.
Interestingly CV510 (6V6) is to a JAN specification but is listed with both a 10E and 110E number.

All a bit confusing but then it was wartime.
