Looks like an early 1970s, French market PL22, but be aware that model designations can vary depending on the intended market.

Peugeot would configure the same basic bicycle with different gearing and accessory options (i.e. single speed coaster brake, single speed freewheel with caliper brakes, 3 speed, 5 speed). It can get confusing. So when looking at catalogues you need to look at the pictures for a basic match, then read the desciptions to determine the applicable options and model number.
