Gary Knutson on left in apron
Behind Gary is Fritz Kayle and on the picture right in apron is Tyler Alexander and in front of Gary with his arms crossed Sid Carr, in front of Sid is Dennis Daviss AKA Deadly Dennis. Gary was getting ready for the 1971 indy 500 in this photo.
Peter Revson drove the #86 McLaren to the pole position and finished a very respectable 2nd in the race. Gary was a crew member on the team as were Tom Anderson and Tyler Alexander and Teddy Mayer and Hughie Absolam.

Nice picture. To fill in a gap, the fellow in the middle in the white shirt is Norman Hossack, who used to mess about in his spare time in Colnbrook developing a novel front suspension for motorcycles, using the principles and construction techniques he learned from building racing cars. BMW Motorcycles eventually adopted and adapted his design, marketing it as the "duolever", though they neglected to credit him as the inventor and compensate him accordingly. He has a website that relates the whole sorry tale.
By the way, I think this is actually Rutherford's winning car from 1974 rather than 1971, based on Norman's presence, the dash layout and details of the chassis by the driver's shoulders.
