Thank you to Gene Lanham for contributing this great old image of a Langley Twin molded plastic-bonded mahogany aircraft. This aircraft had to be hand propped by a strong arm which was an art, according to Gene. The previous quip under this photo about 'Armstrong starter aircraft' meant that a strong arm was needed to hand-prop it.
Thank you to Mark Fidler for identifying the aircraft type and year it was built.
This is an image capture from a 16mm color film.
