Watch the movie its great to learn about how it all began.
I learned this little tidbit from a guy who owned a Model T in Crossfield, Canada.
Henry was obviously no dummy - when he ordered his transmissons he insisted that each one be packaged in an oak shipping
box with some very specific and unusual dimensions. The supplier provided to shipping box at no extra charge just to get the business.
Henry used most of the oak wood ( precut to his specs ) as the floor boards for his cars. Just take the transmission shipping box apart
and make it part of the car - and reduce your costs in the process !
