01/31/2011. From January 1961 till the Autumn of 1965, the Weatherly Aviation Company of Hollister, California, formed by John C. Weatherly, produced nineteen Model WM-62C agricultural aircraft. These were single-seat conversions of surplus Fairchild Model 62 two-seat trainers and most were powered by a 225 hp Continental W-670 radial engine, although a few were delivered with 450 hp Pratt & Whitney R-985 radial engines.
The aircraft is seen fitted with a venture spreader and a small spray boom, while this June 1964 photo, also by W.T. Larkins, shows the aircraft fitted with a span wide spraying system.
