1993 Ayrton Senna McLaren race helmet.
This is an original Shoei Quattro helmet worn by Senna during several Grand Prix, including the 1993 Canadian GP at Montreal. It is numbered at the back and bears all the correct Shoei inspection stickers & dates inside. The top has the special set of 4 air vents that were only used at particular races in 1993 in the McLaren MP4-8 Ford. The radio has been removed but there is evidence of where it was mounted inside the helmet. After the Canadian GP, the inverted BOSS logo on the right side was changed to the standard one for the next few events.
This is an incredible piece of Senna history, and it is expensive, serious enquiries only please. (NF1H)
