Octagon to round 16.5" flared barrel. Percussion lock. One piece stock has a checkered wrist, small clam shell patch box, sling swivels, metal ramrod, steel butt plate and single trigger. Barrel is etched EN EIBER RADE JOSE EISTEGUZ 17 with proof. Stock is very good and complete but forward 11" has been re-attached with wood plug repair as well. Still a very handsome eye appeal.
