You're right about the fork crown - the one on the bike is not from a PX-10. PX-10's did indeed have a crown with epaulets like you show on the Gitane. If the decal says the bike is full 531 and if the rear stays are half chromed, I suspect someone replaced the fork with one from a lesser Peugeot model or from another French model.
