Here’s a picture from the 1959 National Scooter Rally, which appears to show the judging for the concours event taking place on the field. The far left scooter identifies that the Mudlarks SC were taking part, and third from the left is Reg Imrie (who we featured in a past issue of Classic Scooterist).
