The Fitterling cars were all sold to a gentleman in Georgia, who has since passed away. After his death, the cars were all auctioned off. I don't remember seeing any train stuff in the auction, but that doesn't mean they weren't there.
I think that the Kane / Jolson Packard is now its original color, which is a dark metallic grey. The blue color was a typical color being applied in the 1970s.
