Looking at most cars I see the trap door hinge color matches the interior color.
My October 29 1964 Dearborn scheduled build day FB appears to have the hinges body color, which was white, not interior color that was red. Has this been seen before?
Car has been in the family since new and while repainted once, no one ever bothered to paint in the trunk/trap door area, and I see no hint of red anywhere on the hinge. Looks like a black primer with a not quite complete covering of Wimbledon White.
