Dave is correct. I found this description of the '57 Ford Country Squire trim at http://auto.howstuffworks.com/1950-1959-ford-country-squire7.htm A modified version of the 1955-56 Country Squire's fiberglass framing was employed, but the wood-toned Di-Noc shed the horizontal plank look. Side-window frames and the upper tailgate continued to copy the look of wood grain.
