Re: Repairing old butler bell box (annunciator).
Mine runs satisfactorily on 3V (2 x "C" cell). Probably best to find the lowest voltage on which it works, thus minimising any stress on the coils.
By the way, I can't quite visualise what you're trying to do with the glass, but one way might be to print onto transparency and fasten this to the inside of the glass.
