thanks very much for sharing this find!
the PA-10 was a bit of an "orphan" from a sales standpont in my San Francisco Bay area during the boom
dealers had them in stock but sales of Peugeot bicycles seemed to be almost completely confined to models A08, U08/U18 and PX-10
the PR10 was also little encountered "in the field"
we did not see the juvenile or utility models at all
do not know if this may have reflected a distributor or a dealer decision
suspect your example would be likely a '73 rather than a '72 with that model of MAFAC brake lever
