Chevron build record says sold to Bobby Brown of B&B Racing Enterprises, June 1974. The car was badly damaged in an accident at Trois Rivieres in 1974. Brown says that the remains were returned to Chevron in p/x for two B29s in 1975. However, advertised by Brown in May and June 1975 as 'not raced since complete rebuild at Chevron' which suggests that the car came back to him.
