I know this is a oxymoron but what would this be used on. And can it be repaired?
No ammeter were used in Fords until 1919 and if they were made of brass they were painted black at that time. Someone has removed the paint - and the needle is lost, so it would be hard to fix, but nothing is impossible, I guess. I would have looked for another though. For 1926-31 Ford used a smaller style ammeter, so this one would be 1919-25.
The art of balancing the original movement after any repair is not something you can do without very special tools and a lot of know how. Originals can still be found that work OK and I have it on good authority there is a decent repro version available as well. It even appears that the gold paint might have gone through the hole and into the bearing pivot points of the movement to make matters even worse.
Were there ever any period meters which had the embossed scale and Fordl logo? I have never seen anything like that one.

It is not gold paint. The entire meter is polished brass front and back. I do not own it but recently saw it in an antique store and thought it was unusual.
