Having owned one back in the mid 80's, I know what you have. Depending on condition value would be between $300-$500. It was the same as their standard Hawken but with S/S trim/furniture and a select walnut stock. The one I had would hold 3 in groups @100yds w/iron sights. Good luck with yours and don't sell it short, Thompson wasn't made these for over twenty years....
