Wackett was able to acquire the rights for the NA-32 and NA-33 versions of the aircraft, plus the 600-hp Pratt & Whitney R-1340-S1H1G engine. On completion of the mission Wackett returned to Tugan Aircraft, where the Codock design was developed into the LJW7 Gannet six/seven passenger airliner powered by two de Havilland Gipsy Six engines. This was the first of Wackett's designs to enter series production. The first aircraft was delivered in late 1935 and a total of eight Gannets were built for civilian customers and the RAAF. The RAAF took delivery of one new Gannet and subsequently operated another five second-hand examples. One RAAF aircraft was temporarily modified with Menasco engines as the LJW7A during World War II.
