Regarding the Pokora mystery, one of these cars (probably the one in your picture) was at the country garage at Thringstone near Coalville from 1946 onwards, alongside the alleged Duff Bentley. I understand Tom Wheatcroft bought the contents of the garage, including the Bentley and the Pokora. I saw them both in 1946 when I bought a Brough Superior motorcycle from the Walker family— a sort of old-time matriarchy like the Boswells in Bread. They told me the Pokora had been built for hill-climbs and had come over to this country to compete at Shelsley Walsh. I thought it an unlikely story. It looked like the sort of fake racer they used to make for films.
