I'll put it into a museum display. There are several museums out here that it could be displayed in.
As far as value goes. going for it: 1. It has documented history, 2. It came off a Zero, 3. its a large piece
going against it: missing data plate, No red meatball, condition
I'd say it worth about $1,000.00 It all depends on the buyer.
Please keep us informed as to what happens to it. what it sold for
