Can't help with dating the piece but man, it's sure a beaut!
It's in nearly new condition. Cost me $25 at the estate sale where I found it, and based on what I've been able to dig out , it was made sometime in the 60's or possibly earlier. The company redesigned it in the 70's or later, and sold the new design in the same box. I've been told the company moved all production to China in the late 80's. I don't think there's many of this model around anymore, since I've searched practically the entire web and not found one yet.
