Motorcycles at Silverstone

There were no motorcycle races at the Coys International Historic Festival meeting at Silverstone in July 1994, but this is a photograph that I took in the paddock that day.

There doesn't appear to be anything in the programme of the event about these bikes, but the white number 11 on the blue background indicates that the AJS is a 350cc machine whilst the white number 9 on a green background tells you that the Royal Enfield has a 250cc engine. If it's still kept the same registration number 362 WNK belongs to a 1958 499cc BSA.
