It was a very small black car, open topped. I think it was an Austin. Him and his pal shared it. His nephew -- my uncle -- fitted the flashing indicators and also an electric klaxon. He was into that sort of thing as a teenager. He was always rigging up telephones etc and he installed lights upstairs in the house because it only had them downstairs.
A peculiarity of the house was that the mortar was black and conductive.
