Thanks for the link spacedoubt, some very interesting stuff but I couldn't find a match to the item I have.
I took the advice of Toromos to see if a battery would make any indication on the dial.
I hooked up a couple wires to the bolts and started with a small lithium battery and got nothing, and then still nothing but a small wiggle with a new
When I hooked up the Duracell AA I got a needle swing to about the 5 point on the dial, and then reversing the battery the needle swung the other way
about the same amount.
Obviously it's some sort of very old DC volt meter.
I'm very curious just how old this thing is now. It's very well constructed and still in working condition it seems, though the hard insulation on
the main wires from the coil are a bit cracked from age.
I think I'll do a bit more research on the manufacturer to see if I can find out anything about them, or at least some reference to that company.
Any other ideas or clues will be appreciated.
