If anyone sees a 1945 Annual Report for Willys-Overland, be advised that there is a section in it that "announces" the 6-66 (for 6 cylinder, 66 bhp flathead engine) with pictures of the prototype and features that include a fold/swivel front seat to allow more room for rear seat passengers to sit in. I had a copy that I loaned to Brooks Stevens for something he was working on at the time of his death & never got it back.
