...without some sort of provenance, I don't understand how someone here ought to turn up who knows more about it than you already know.
Certainly there are a range of opinions here with regard to values, and collectability, etc., etc. It's not an item that comes up for sale often, so how do we estimate a value, unless it's a "value to me".
It's not my size, so I'm not trying to knock it down on value. I just don't think you're gonna get better information here on a one off.
