1047b has raced in SVRA, HSR, VSCDA, and will continue to do so(I heard it from the horses mouth)because it is made from factory parts and has the original 1047 chassis tag. This makes it a genuine Gt40 vs. an original gt40.If George was not the ethical fellow he is, he could have presented the car as 1047 vs. 1047b, but he is a stickler for the truth, and it does not hurt that George has so many other significant cars, gt40 and otherwise.
It is a real gt40, the same as so many other gt40's that have had their chassis replaced, but George keeps everything above board.My Mk 1 spyder,by comparison, has some original parts on it, and occasionally vintage races in HSR/SVRA, but it is a replica and is only allowed to race when the grid is less than full and there is no chance of it winning. The price is $295,000.
