I saw one on craigslist the other day. A Sears Free Spirit built by Puch. It was lime green or like a faded gold with Simplex and other french components. Full 531.
Pretty cool seeing a Free Spirit with 531. A high end department store
It was listed at 150 and sold within a couple of days.
It has probably already been answered but OP I don't think yours is a 531.
It looks more like this one VVV Still a handsome looking bike. And @ RobbieTunes; I love this long sweeping forks too!
