- 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 teh serial number 11135. It's beautifully made, almost mint condition and makes an excellent ornament.
Very pleased to get some info on it.
