Originally US Navy HSS-1N 143957 that was withdrawn and stored at AMARC in 1969. From limited information, the helicopter looks like it went to one of the salvage yards near Tucson, AZ in the '70s and was sold to become N9043N . Pictured with Moore Aviation working as a crop sprayer. On June 24, 2012, as the aircraft lifted off for a flight with another operator, the engine caught fire. As the pilot set the machine back down and exited, it was consumed by fire.
