1. Converter - Large hollow cylindrical converter. Set into a rectangular base which rises into a trapezium shape to support the cylinder. The base is hollow underneath with four empty screw holes in fortified corners. There is a crossbar through the centre of the rectangle with a large hole in the centre and three screws (one on one side of the hole and two on the other). The hole is larger than the screws an unlikely to have contained a fourth screw. Embossed on top of the base at one end are the letters “BRC”, two more figures which are indistinguishable, then “100”. The cylinder itself has two large screws on each side, and a metal plate attached to the top with two small screws. The markings on the plate are heavily worn, but some of what is discernible reads “230 D.C.” and “AMPS”. The end of the cylinder is also marked with “H.V” and “EA-80925” There are three screw holes at the top and base of each end of the cylinder. The ends of the cylinder also have large metal protrusions in a “U” shape. Each side of the “U” has a large metal screw going through it with a black screw cap on the outside. The base of the “u” has a circular plate with four screws and a long twisted wire attached to the top and base. Inside the “u”, extending towards the inside of the cylinder is a large circular gear which is attached to the large, wire, rotating centre of the converter.
2. Metal plate - Warped metal plate, bent inwards at two points, then outwards at a third. Heavily eroded with a number of holes.
3. Metal plate - Flat, heavily eroded metal plate. Has one empty screw hole, with a second screw hole and remnants of a screw beside it.
4. Metal plate - Small section of metal plate, heavily eroded. Contains fully threaded screw which is only threaded 2 mm through the plate with the remainder of the screw protruding above the plate. Screw has a flathead crease and a mobile metal washer.
5. Metal pin - Solid metal pin which is threaded for 9 mm on either end. One end has a single hexagonal washer threaded 3 mm in.
6. Screw - Single screw with a small amount of eroded metal plate surrounding it. Screw is fully threaded with a flathead groove.
7. Screw-Single screw (see artefact 6) with slightly more eroded metal plate protruding to one side of the screw.
8. Screw - Single screw (see artefact 6 and 7) with no metal plate surrounding it and a metal washer along its length (not attached/fully mobile and removable)
