Back in the late seventies or early eighties I owned a butt stock by this maker , In my memory it was very similiar to your gun . The bbl. was missing, but it was at least 1 1/4 at the breech with a taper . Can't recall the trigger guard , but the shape of the stock , patch box , inlays , and butt plate were very close to your rifle . At one time I had a black and white photo which I may have pitched . Sometime today I will go through a bunch of old photos to see what I can find .. LP
