I have other antique doorbells. Please look!
Antique Brass Electric Doorbell made in Germany ca.1900.
Traditional design which can be mounted vertically or horizontally.
Measures 2-3/4" tall by 1-1/4" wide by by 1-1/4" deep.
The pushbutton at the center was upgraded for decades of worry-free service.
Excellent, used, antique condition!
