Other than the couple of photos from the introduction at the Racing Car Show, these photos from Silverstone Trophy race May 11th are the earliest photos prior to running Le Mans. I was interesting to see the original configuration.

Small problem back behind the house today. Actually, two of them which greeted me from 10 feet away when I opened the door to leave. They were quite large.
Then there was this train wreck on over the hill... interesting day it has been ha.
Found this outstanding article on an M1 Mclaren. Thought you other fans of Bruce's might find it interesting.
