A quality solid brass and lacquered brass Nalder Brothers & Company, Westminster ballistic galvanometer. Although the galvanometer is in need of restoration it is basically in extremely good condition with original finish throughout. As you can see from the images the galvanometer has its floating core and height adjuster. It requires a small piece of mirror fro reflection purposes through the glass window. It has its two original knurled tripod adjustable feet and connections are made via two heavy duty lacquered brass screw terminals insulated on ebonite.
The coil can be raised and lowered by the brass plate to align the mirror with the viewing window. The solid brass turret has its two knurled locking screws but has had a replacement glass. The turret again is in original lacquered finish and nobody has attempted to mess with the instrument.
