I recently purchased a 1926 RHD Cadillac 314 Limo. I has also got build sheet from GM archives. Previous owner didn't have much history on car other then owning for 7mons an bought from another person. I plan on getting it running an hope to have few period correct fixed (paint, trim, etc). But after viewing build sheet it didn't list any options though there are the upgraded wire wheels, leather wrapped leaf springs, 2 boxes (1btry,1jack), RHD, rare curved partition window. But nothing but RHD is listed. How do I find out possible value now or what might be. Original paint said Duco Kangaro Brown but all the search I found didn't show a Duco KB. Any help is greatly appreciated.
