Description

The main component is a tall square wooden box on an enlarged base, painted black, with a metal frame around the top. A rack and pinion mechanism on one side controls a dial that has handwritten numbers from 0-240. Inside there is a black cylinder with a conical grey top, attached to a long thin electric cable and two metal fittings one attached to the pillar and another detached.

Also present are a square card envelope and a rectangular yellow card envelope. The square envelope has a black card square of the same size, a black card frame hinged on a sheet of white card, two large wire mesh squares, a smaller wire mesh square with a central circular aperture, a wire mesh rectangle with a concave four-pointed star shaped central aperture and two wire mesh circles, one with a smaller round hole cut out of the edge.

The other envelope contains two thin wires with loops at one end and cotton wool at the other, a thin wire that is hooked at one end and has a paper hexagon at the other, a wire with a loop at one end and a blunt blade at the other, a glass negative showing a man, a woman and a dog, a square metal and square glass plate both with a 3x3 grid on a black background; the metal one sits in a square metal mount, a small black and white photograph of a church, a card rectangle with a central aperture and a card sheet with instructions.
