Not sure if this is the right place for this given the different Chevron threads but it appears that Riccardo Patrese's European F3 Championship winning B34 is alive and well.
I was recently contacted by
someone who had bought chassis 06 which was later driven by Piercarlo Ghinzani. According to Riccardo this car was sold to Ghinzani after it won the Euro F3 title at Vallelunga, and was then used by Piercarlo to race Riccardo at the final round of the Italian F3 championship at Magione, which Riccardo won.
Where the car has been since I'm not sure if anyone knows?
