's sole aircraft design was actually a collaborative effort of three engineers: Ben Anderson, Marvin Greenwood & Lomis Slaughter Jr. The name of the last member of the design team was not included in the product name as it was thought it would not boost sales. The prototype first flew in October 1947, but plans to mass-produce the aircraft were interrupted by the

. Eventually, only five more examples were built before Anderson Greenwood abandoned the project in favour of producing aircraft components for other manufacturers. The aircraft's design placed the wing behind the cabin and allowed easy entry via automobile-like doors on each side of the cabin. The propeller is well protected and provides safety on the ground in comparison to

. The aspect ratio of 9.6:1 was high for aircraft at the time it was designed. The wing has 7 degrees of dihedral for directional stability. A four inch propeller shaft extension allows the engine to be mounted closer to the aircraft's center of gravity. The nose gear steers through the control yoke and not the rudder pedals. The AG-14 has very good visibility and one reviewer termed it "amazing". The aircraft was

The five pre-production prototypes were the only examples built. The retail price of the aircraft was set at $4,200 - $4,500. In 1969 one AG-14 aircraft was acquired by
