Well, to start with the number is CUT 7, and yes there are two in existance. Dick Protheroe had originally an E type coupé and transferred the number to the low drag coupé when he sold the first car. The original, with a blue nose, still wears the number CUT 7 when it races as does the true low drag owned by Michael Cowdray. However, there is a gentlemen's agreement between the two owners that if both are racing at the same course the same weekens then the low drag coupé takes precedence and the other removes the plate. As regards low drag coupés, there were several including the Lumsden Sargent car 49 FXN (also owned by Michael Cowdray) which has a much longer nose. Here are photos of the three. Don't also forget the Lindner Knocker car too.
