Antique 3 Magnet H 22A Crank Wall Telephone Magneto which is as tested functional and as needing only the 1/4" hand crank for installation into the wall telephone casing. The magneto measures 5" in height 3" width and 5" in length from threaded stem of the crank to the mag output screws. Conditionally, the magnets have some finish loss and one of the side plates has a chip to the metal at one corner, but otherwise the magneto is in well preserved shape and serviceable as replacement for a missing or dysfunctional magneto.
