The Labour government, in what could be classed as a treasonable transaction, sold 25 Nene engines to Russia in 1947.
These were sold on the caveat that they were not to be used for military purposes.
P+W also acquired a licence to produce Nenes.
There is also the story of Russian delegates visiting the RR factory in soft soled shoes to pick up swarf form the manufacturing process,
so they could replicate the materials later.
A lesser known story was of a U.S. delegation (IIRC) that came across to learn about jet technology and went back promising
further co-operation with their UK counterparts. Nothing more was ever heard from them!
