Two sheets, printed both sides (only one side pictured here) of very detailed plans which apparently appeared in Air Age Magazine. Plans were drawn by William A. Wylam to a scale of 1/4" = 1'. There is an indication that this model may actually have been built by Ford over the period 1926-1931. Plans sheets are 15"x21.5" printed on slick, heavy paper stock, four folded. Very good.
