This is an antique, 1910’s or 1920’s, wall mounted, space saving telephone. There is no name on the telephone. I am assuming that it is Western Electric due to the research that I did on it. It does have a model number, G4.
As far as condition, it has not been tested, therefore I cannot say whether it is in working condition, or not. It would be a good project piece, or a nice decor piece.
If you have questions, please e-mail.
