From N.A.R.T.'s internal archive comes this evocative original file from the North American Racing Team (NART) covering the 1973 Watkins Glen 6 Hours. This race, part of the World Sportscar Championship, saw the continued collaboration between Luigi Chinetti’s team and Ferrari, with entry #8 driven by Sam Posey and Jean-Pierre Jarier in a Ferrari 365 GTB/4 ‘Daytona’ (chassis no. 16407), and Ferrari 312Ps chassis numbers 0890, 0892, and 0896.The file includes Goodyear tire pressure logs for cars 5 and 8, annotated with handwritten lap data and tyre metrics, a weight scale slip from Howe Richardson Scale Co. detailing the GTB/4's loaded weight with 260 lbs of fuel, handwritten notes recording chassis numbers, driver lineups, and technical annotations. All housed in the original internal Luigi Chinetti Motors folder labeled “Watkins Glen '73”, with annotations linking to team logistics and component records.
