Nene/Derwent to USSR: see my #166.
UK also bartered various aeroplanes, good and not so, for Peron-Fascist Argentina's beef. We were hungry and cold in 1946/47, so could not be picky about customers. Massey-Ferguson tractors, Morris Minors, Cossor/EKCO brown goods were not yet ready to burst on the world export scene. Great hopes were placed on Aero, especially turbines, to earn the $ we needed to survive. See the Brabazon Committee suite of civil Types.
For me, the 1946/47 turbine blunder was not this, but was Cabinet's 7/47 denial of a modest $ commitment to permit Bristol to licence-build L-849 Constellation, initially with Centaurus, then Theseus turboprop.
