"How about this display from the 1934 edition of the Century of Progress, Tony? As I mentioned here before Henry dragged his feet and didn't go to Chicago in 1933; but in 1934 this complete Fordor was displayed in cabinets for all to see. The series of photos show everything, for example a lower seat spring assembly was broken down to individual pieces, the radiator as tubes and plates (for the fins) etc. Those were the days! "

Notice the valve seats in the photo!

That is a cool display! I'd love to have that cutaway flathead in my shop too!
