I purchased this on eBay a while back (see link). Love the hat. Lightweight, very thin, papery felt. Crisp. Thin edge banding. Cool taupe color (although on paper tag inside band it refers to it as "NUT" - probably more appropriate for me). Anyway, inside it is stamped Royal Stetson but that's not a reference to a style or model is it? On the hidden paper tag there is typed; "STREAMLN". Is there a Streamline or Streamliner model? I've never run across that designation before. Your thoughts folks?... Thx!
