Nothing special, unfortunately. You're on the right track, though, but just want a little older. Typically (I'm sure there are some instances where this is not true), if tiger stripe has any labels, it's probably post-Vietnam civilian stuff. Most of the good stuff will have no markings at all (or they faded away), or will have a small black size stamp near the collar on the inside. Those are late 70's-early 80's civilian marketed stuff.
