Interesting 14pp, 8.5x11" report with photos, illus and specs on the conversion of a 4-cyl McCullough 4318A drone engine into a helicopter engine for a one-person helicopter. The report is housed in vinyl sheets with a heavy black plastic cover and comb binding. Likely this was also used as a sales document. Excellent condition and quite rare.
