I'm in the process of reupholstering my '50 P-20 club coupe. We dismantled the seats and found the original build sheet rolled up in one of the springs of the driver's seat-back. Dated 12-15 at the Dodge-San Leandro Plant. It's a SP DX CL CPE, trim 949, 3.9 gear ratio, body by Briggs, Accessory group 1, and deluxe heater. "Special Instructions" has a type written "FCR" and a hand written "731". It was shipped via truck to a dealer named "Buxton" in Portland, OR.
It has boxes to check for individual accessories, several of which are on the car, but unchecked on the sheet. Maybe they were included in accessory group 1.
Anyway, it was kinda cool to find that. Now I know a little bit more of the history of the car. Anyone know what the "Special Instruction" notes mean?
