Ford doesn't have an archive system like GM or Daimler-Chrylser, especially since they're cutting out everything they can due to all their red ink. That's why we're here - we care enough to help. It's also the reason why VTCI has published the 1961-1963 Original Factory Specifications Manual, which contains information on interior/exterior colors, finishes, engine detailing, chassis components and MUCH more! You need to get a copy of this if you are restoring, detailing and preserving one. It is available through VTCI's Country Store to VTCI members.
As for colors, Roadsters were available in Silver Mink with Silver Mink vinyl (50), black cloth/vinyl (76), black vinyl (56), black leather (86), red vinyl (55) and red leather (85) interiors, according to a revised Dealer Facts Book dated 11/15/62 and revised listings in the Color/Trim showroom album dated 4/1/63, with a choice of white or black convertible top. This information is listed in chart form, along with other interior/exterior combinations, in VTCI's 1961-1963 Original Factory Specifications book. What's needed to complete the documentation chain are copies of the original color/upholstery listings that would have been issued in late summer 1962 to confirm that there were not additional interior choices.
There has been a question recently regarding availability of Blue trims and a blue top on the Roadster when painted Silver Mink. As noted above, color/upholstery listings in dealer sales literature does not indicate that it was. However, at least one instance has been reported of a Silver Mink Roadster sold with a blue leather interior (82) and documented by its Gate Release (I do not have a copy of this for verification). This most likely was a special order, which could be done by a buyer, but usually would be noted as such with a DSO number more than two digits long and also noted on the ROT/build sheet and invoice. Silver Mink vinyl (50) looks very close to blue (52-vinyl, 82-leather) until you put the two side-by-side. And, you could only get blue convertible tops with blue interiors.
