Early WW2 ammeter?

[BCA]

Found a couple of these ammeters, G104-05-00030. 2.5” gauge diameter. What application might they have? Any interest? Thanks, Brian

G104 suggests Sherman tank, but I don't have definite knowledge.
At +/- 150 amps display range it has to be something with more than a car battery - weren't CMP ammeters +/- 30 amp?

Along Grant’s thought line, Brian, armour typically runs wireless equipment from the vehicle electrical system. No independent wireless charging systems.

Did ‘Command’ Shermans run two wireless sets? If they were both run from the vehicle electrical, perhaps said electrical systems were beefed up versions of the standard Sherman setup and that ammeter might be part of that type of installation?

Perhaps? Maybe? Maybe not?

Could it be for the charging plant for one of the Sherman variants?

these are for early Shermans , and for the RAM tank , they are dash mounted .
I would be interested , but shipping might be a problem because the dials are radio active .

Originally in M3 medium where the others inherited it from.
