The mod 49 was introduced in 1949 and I think remained the top model until 1957, when the mod 57 came out. However, like many French manufacturers, Stronglight kept making older models, simply pushing them down to cheaper bikes. From the headbadge, your bike sounds like late 70's, so the mod 49 could have been original, pretty sure this model was made into the 80's. One consequence of this practice is that you will see Stronglight mod 104 and 99 with old Stronglight extractor thread from the days when they were top models, but also examples with Campy-compatible thread from the 80's when they had become mid-priced cranks.
