Stronglight cranks wre available with English threading from pre WWII days.
Constrictor imported the 49D model from about 1938 with English pedal
threads. After WWII supplies did not resume in England until 1950 but I
would be pretty certain that both types of thread would have been made
only France persisted seriously I think with their different pedal
threading.
