This is a real Bakelite doorbell in Kelly green. This is a recreation from the 1930's, complete with angular diamond motif decor to the sides.
Measures 3 1/2" tall by 2 3/4" wide. Recessed name card slot is 2" wide by 3/4" tall.
The button is rated 1-24V, for standard doorbell circuitry.
A wonderful finishing touch.
