If they survived in the Soviet Union, they must have been pretty good.
Charles Sorensen went over to there to help them. He tells the story in his book, My Forty Years with Ford. They were already making Fordson tractors that they had copied. The quality was inferior. He also saw people who had worked in the Ford plant in Dearborn, immigrants who went back, I guess, so they were "advisors" to the Sovs. His book is a great read. Out of print in hard copy, but it may still be available in some libraries. You can find a e-version. I got mine from Barnes & Noble.
