Designer Richard Hardin with his Ace 300, completed in March 1931 at the manufacturer's 'Ace Airport, formerly Murphy Airport, at Telegraph Road and Atlantic Boulevard,' Los Angeles. The 'companion' Ace 500, NX953, was a tandem two-seater. Information from aviation historian John Underwood corrects confusion about the model numbers. Aerofiles is mistaken in linking these aircraft to the Aircraft Engineering Ace K-1 biplane, built in New York City in 1919. Photo from: Nationaal Archief (Netherlands)
