Antique Test Meter bearing the inner plaque "designed and constructed by EE Triggs April 1918"

EE Triggs worked alongside Marconi in this period and seems he constructed this piece as a one off test model. Homemade and scratch built, its inner "core" is embedded in wax, original glass panel to the front and mirror behind the engraved panel. Beautiful piece with dove tail joints, brass fittings and bakelite front. Sold as seen, for restoration or display, will need tested by a qualified engineer before using. A genuine one off.
