The Gordon Keeble was the result of a partnership between John Gordon and Jim Keeble.  The body was designed by Giorgetto Giugiaro and the car was powered by a Chevrolet V-8 engine.  Approximately 99 cars were made between 1964 and 1967.  The tortoise on the car badge comes from a test drive, when a tortoise in the road ahead was rescued and put on the bonnet of the car, where it promptly left a “message”.  This was interpreted as a sign of good luck and was therefore used on the company badge!  Thanks to David Yeomans for this anecdote.
