Hi all,
My dad bought NC37803 in the summer of 1977. It had sat in a hangar in west Texas since 1957 or so. It was extremely original.
I distinctly remember when I helped my dad dissemble it that there was virtually no Philips screws anywhere on the entire airplane.
It seems to me that we literally only found a couple.
As for its colors. It had a black fuselage and rudder, with the factory standard three parallel stripes down the fuselage. It had red wings and elevator.
You can see pictures of it on this forum in the "pictures wanted" section.
Hope this helps.
Dan
