A really lovely country house 
butlers/housekeepers bell. 
In lovely condition with a reverse painted glass window in black and gold. 
The moving flags are all present and still move. These could possibly be made to work again using a very low DC voltage from a battery and a bell push (must not be connected to the mains, under any circumstances). This is a job for the electrician. 
Alternatively, it would look great just as a decorative piece above the door. 
Measurements: 33 x 7.5 x 19cm high
