This Galvanometer was made in 1870 and installed at a Coal Mine, It was used as a signaling aid. I worked on the replacement signaling system in the early 1970's. I removed this Galvanometer from the head of the mine drift, where it had worked without fail for some 100 years.

It is part of my quirky collection of old electrical bits and bobs.
