Your comments:

• I have a working galvometer just like the one show. Numbered 1884 and marked London it was used in the telegraph section of the NZ post office Dunedin.

• I've got one!
  
  No scale at the top though but otherwise it's exactly the same. Got it for £3.50 from a junk stall in Inverness Street market in North London years ago, and it still works.
  
  Very pleased to see it's made by the Silvertown Works. Their mentioned in a number of books I have about ancient instruments.
  
  The one I have has GPO and the serial number 11135. It's beautifully made, almost mint condition and makes an excellent ornament.
  
  Very pleased to get some info on it.
