More than a few modern trade guns have been made, and sold, to museums in the U.S. and Canada. They were not intended to be thought of as originals, but over time, records, get lost, directors, retire, or die, and the gun gets bestowed with honor it hasn't earned. Green River Forge bragged about their guns being sold to museums, to show what an authentic representation of a very rare indian trade gun really looked like. I'm sure if Green Rive guns ended up in museums, North Stars, did as well. It is interesting that years ago, trade guns, were extremely rare finds at gun shows, and sales of collections. But, now they approach being almost common.
