My dad got the rifle in the photos below at the last Fond du Lac Wisconsin gun show. It is a Ruger #1 with some custom features. It has been re-barreled to 30-30 Winchester and someone modified the buttstock to look like a Schuetzen rifle.
Supposedly, it came from an estate of an active single shot shooter. We are hoping that someone here might recognize the rifle and point us toward the gunsmith that did the work.
