Rare Victorian Military Galvanometer by Elliott Bros.

A beautiful late Victorian instrument made of brass with a brass dial and compass type hands. It has two screw connectors on the sides which are linked by a thick copper or bronze component inside the heavy glass casing.
Basically a Galvanometer is an early Ammeter an instrument to measure electrical current. Used with detonating explosives and early telegraph communications in the military.
This Galvanometer was made by the Elliott Brother London and patented in 1885. It has several markings on the side; first, the broad arrow with the numbers 27 with an ‘A’ added later. It also has ‘RA’ scratched into the side, so it was obviously at some point used by the Royal Artillery. These were also used during the first world war for measuring the electrical current used to detonate mining explosives.
A very interesting and rare piece measuring 3.5 inches in diameter.
