As well as the Radio (as it turns out) from the previous post to this, my brother and I also uncovered a Westinghouse Dynamotor.
This wonderful contraption is a low voltage DC motor coupled to a high voltage DC generator. These things were used in WW2 and may well have found its way back from the war with my Dad, along with assorted bits of mine, which I remember being used as door stops around the house. He was in the Royal Navy on a motor launch - mine sweeper in the Adriatic for most of the war.
My brother remembers my Dad taking this on camping holidays so that he could use his electric shaver.
So, why not I thought, lets fire it up! And it still works well and here is the video evidence to prove it.
