The only B-10 version still in existence is this model 139WA export version sold to the Argentine Navy in 1938 (their s/n 0080), and used for training ground crews as late as the 1960s; it was last used as a ground-training tool for Argentine engineering students at the "Jorge Newberry" National School of Technical Education, No. 1, in Buenos Aires. It was acquired by the USAF museum on 21 August 1970 and is now displayed restored in the markings of a B-10 from 1934.
