Email correspondence from Pani Tsouris, McLaren F1 Senior Technician at McLaren Special Operations, identifies this as an early variant of a bonnet for a McLaren F1 road car. The seller believes it was used by the development team for heat mapping and protecting the brake fluid and clutch fluid reservoirs from thermal soaking. Acquired by the seller in 2008, this McLaren F1 bonnet is now offered at no reserve in London, England.

Constructed of carbon-fiber reinforced plastic, the outer surface of bonnet is painted green. Scratches are visible.

Exposed carbon fiber, gold foil tape, and mounting holes are visible on the underside. A copy of the aforementioned email correspondence is included.
