H. W Sullivan of London Wheatstone Bridge Galvanometer Type T1102
W Sullivan of London Wheatstone Bridge Galvanometer - Type T1102. The Company manufactured high precision electrical standards of inductance, capacitance and resistance, and instruments called a'bridge' for accurately measuring these three components. This is an extremely rare piece I have only been able to find one other the same. There is a cracked piece at the top of the face board but does not affect the mechanisms.
