The Warbirds Registry has a page on the history of T-31 (serial # 44-35893) and T-36 (serial # 44-35456). Of note, Air Spray purchased both of these A-26 tankers from Conair. Air Spray bought the
A-26 (serial # 44-35456) that was to become T-36 from Conair in 1983. Before that she flew as Conair
T-26 from 1972 to 1983.

A-26 (Serial # 44-35893) flew for Conair as T-31 from 1974 through 1982. Sometime in 1982, Conair sold her to Air Spray, where she kept her T-31 designation. She flew for another twenty years (give or take).
