More on the 10A/ 10S/ puzzle. A recent item for auction was described as follows:
Testmeter type 'E' Ex Air Ministry Reference Number 10A/10613 Serial Number E19406 Date marked 1944 on scale plate.

Although the instrument does not appear to have 10A/10613 on its case or instruction plate, the part numbers for the fuse, clips and prods have 10A/ references rather than the 10S/ ones in AP 10955H Vol1 Section2 Nov1943. Attached is picture of instruction plate.
