A family member is trying to identify a gauge that we assume has come from a vintage aircraft.

Could anyone tell me what it is, what it does, and what it's from?

Thanks. :)

It looks like a Sangamo Weston Frequency Meter off a Britannia to me.

Used to monitor the frequency of the 200V AC. Similar used on the Vulcan, and many others.

Definitely not Vulcan. These are Vulcan with full scale reading... most likely something 1950's civil

This should have a part number below where it says 115V, it will be black writing on the black dial, I think from memory this will be S109-?-???, under neither this there should be a serial number normally starting with two letters.
