Built as a civil aircraft and registered NC8943H, it was one of 83 of the type bought from North American by the USAAF for use as liaison and staff transport aircraft and designated L-17A, and in this case allotted the serial 47-1312. It was later fitted with new brakes and fuel tanks by Schweizer Aircraft Corporation and re designated L-17C. Later civilianised as N6724C it had a number of accidents, and was most recently restored by lately deceased Milwaukee Police Sgt. Burton K Ottow whose name it still wears. It was being offered for sale at Oshkosh with the proceeds going to his estate.

"Lil Bill" at Planes of Fame Museum. The military L-17 Navion started as the civilian 185hp NA145 model. It bore some resemblance to the P-51D, but had a tricycle landing gear. The USAAF became interested in 1946 and ordered 83 for observation, liaison and as trainers for ROTC, plus six as unmanned drones. Ryan Aircraft acquired manufacturing rights in 1947, delivering the L-17B and L-17C. In 1960, TUSCO acquired rights and made the L-17. By the time production ended, around 2,500 had been built.
