1952 Vagabond colors should generally be the 1951 color. This is because in many cases, the bodies were built up as well as other assemblies (like the front clip) expecting to be 1951 model years cars, but no orders from dealers came through for the various combinations. It was like the 1950 model year, where the company had thousands of finished bodies but nobody wanted the cars.
Also, please note I met with Mike Knittel over the weekend duringthe Mid-Atlantic Region meet. We discussed the various formats submitted from different members and we agreed to the following:
1. The format suggested by Jim Betts would be the "standard" format for a document with a current working title of "Restoration Guide". This would include pictures of various features specific to the make/model/year covered. There would also be a general section, that may end up mostly pictures, showing general items such as condition of chrome or paint, and how condition reflects point loss (a little pitted chrome, badly pitted chrome, chrome with areas pealing off or rusted, etc).
2. The management of the KFOCI would make a series of policy decisions covering things like "acceptible vs. original" because you cannot get a something any more and demand would be too limited to make reproduction viable, retrofitting of options, etc.
