At least the second prototype of the
Iljushin IL-28 jet bomber was equiped with Rolls Royce Nene jet engines, because the Klimov engines of the first protype were too weak for the heavy plane. Later versions got stronger klimov engines.
Don´t know how the russions got the engines, maybe they have won a billiard game, more likely they won a wodka drinking contest or russian roulette
