The four-seat Paulic XT3-B NX21726 was originally built in 1939 as a joint project of John W. Thorp and Rudy Paulic. A side-by-side trainer planned for Boeing School of Aeronautics in Oakland, where both Paulic and Thorp worked.
It was dismantled after several test flights and stored until July 1958, when it was redesigned and rebuilt by Paulic as four-place retractable-gear T-3B-1 with a 190hp Lycoming O-435 engine and re-registered NX6497C.
