1967, Dick Thompson driving for team Shelby. Carroll is looking dressed to the 9s, but check out the rest of the details in the pits... like the tank level indicator hose

I may be wrong, but it looks look a welder with Oxy/Acetylene tanks, a floor jack, one pit crew member with an air impact wrench, and 3 guys loading fuel into the trunk gas cap filler.

I think it's a classy look to have the fuel barrels in the car colors too.

This was at Lime Rock according to the gallery of photos it's mixed in with
