Picture of the week..........Seeing Red!

This picture was taken in the mid 60`s, I think the venue is Snetterton race circuit though If anyone recognises it I would like confirmation. This very period shot shows three Fairthorpe Electron Minors book ended by an Electron at the far end and Willie Simpson`s Electrina nearest the camera. Amongst the Minors is John Allan`s much raced Ford engine car. Red was obviously THE colour to have if you owned a sportscar! Can anyone identify the Electron, either an owner or a registration number?
