What its For?
The 2 posts in the back and patent number, 1970889, would indicate that its an ammeter . Label reads do not charge over 7 amps if only one bulb is charging. Then it has two dials for a left and the other right bulb
The past is a great place and I don't want to erase it or to regret it, but I don't want to be its prisoner either.

Re: What its For?
Battery charger that used 2 rectifier tubes maybe.
For example, the KR Wilson used for charging magnetos and batteries had 2 rectifier tubes that depended on what operation it was doing, could use one or both. It does not have that gauge but just a suggestion.

I know the voices aren't real but damn they have some good ideas!

You might be right, they were mercury bulb rectifiers, and if one out of 2 had failed you would overamp the remaining bulb. I think.

Patent number led to this battery charger. That meter is featured in the patent drawing too.
