[CR] Components on a Peugeot P5 Iseran

Would a Peugeot P5 Iseran mixtie have had a Shimano 600 BioPace crank set? From my research, the time frame is appropriate; the bike is probably from '83/'84 and the BioPace cranks were made from '83 - '93. Or, would it have (more likely IMO) been a Nervar ? This bike that I picked up has the BioPace right side and a Nervar left arm.

Also, what brake set might it have had, originally?

Thank you,
