An antique brass servants bell, steel sprung and mounted on an iron bracket. For use with a mechanical pulley system. 

The bronze bell is sprung loaded and secured with a copper flat head pin. The brass bracket is stamped with several numbers and initials but I can't quite make any out.

Fully restored and in full working order.
