i think i figred it out
it's a 1976 bill stephens chair. I ended-up buying it for ten bucks. I cqan't find a picture of it on the web, but it's a lot like his arm chair, 1305U, only with a four-star wheeled base http://www.knoll.com/museum/prod_museum.jsp?prod_id=345
Interesting how much these guys "borrowed" from each other, and how long their stuff was produced. L:oook at the arms if this chair compared with the pollock chair, compared with arms of the Eames aluminum group chair. This chair I have is like a plywood aluminum group chair with a pollock chair base.
