That's a nicer bike than an Iseran. Peugeot's lower-end models weren't normally equipped with chrome forks. And it looks like maybe a Reynolds tubing decal just above the downtube shifters.

If it's Reynolds 501, maybe a PH-501 or PGN-10?

If I was a lot taller and looking for a bike to ride, I'd probably be all over this at $150.
