Telegraph Equipment

 I'm unsure as to what this object is exactly, but it might be a telegraph relay or repeater? The name of the manufacturer dates this to after 1880 when Siemens Brothers & C. Ltd was formed from the earlier company.

It was kindly donated by Simon Cole from Westcote Barton.

 

 Here are some pictures...

 

 Four alternate base connections (of the eight) going clockwise are LOCAL, LOCAL, - and +.

Does this labelling indicate that the long incoming lines enter at + and - , with a second line in series with an accumulator and limiting resistor originating at the pair of local connections?
