A bicycle produced that late in 1983 would be a 1984 model. A 1" seat post indicates plain carbon steel. Definitely entry level, as suspected.

As for the Mistral, a Huret derailleur, if original, may indeed indicate 1972. The 1971 CCM Lightweights used Huret Allvit, though the Mistral was not in the line-up. In 1973 the Mistral used Simplex derailleurs. However, the 1973 Mistral did not use pump pegs or that crank according to my literature. The 1974 model shows pegs and that crank. While I don't have the critical 1972 literature, I would think that the lack of pegs indicate 1972 is unlikely, since they were not present on the 1972 model.

Huret derailleurs generally do not have date codes. However, there should be a four digit date code on the back of the cranks. And I can date the frame by it's serial number. So, we should be able confirm the model year.
