I've now got a set of rather rare wheels. I bought them from the collection off 1002,... the GT40 known as Felix because of its registration mark "FEL 1C". A reputable source said they were F3L wheels and I was going to use them with road tyres, keeping my magnesium BRMs with those Dunlop crossplies for show. However, they have "GT40" and "KAF" cast into a couple of the spokes. They are 10" & 11"x15" and turn out to be original early GT40 alloys, a factory alternative to the Borani spoked rims.
