Can anyone with a robust knowledge of vintage jackets tell us about this jacket's history? I always thought it was a 1980's Cooper design but I read on another site that someone had one of these made in the 1950's, possibly from a company in Pennsylvania. I have never seen one that predates the 1980's but that doesn't mean they weren't made before then. Anyone know? Everyone for Lost Worlds to US Wings sell these. Here's the Lost World's version. The back is a half-belt.
