Thanks Stu. Yes, that join was there when I bought the gun. Whoever did it did an excellent job. This one seems to be a favorite with other shooters at the gun club. Light weight and very accurate.
BARREL LINERS: The only reason to add a liner is the original barrel is in too poor of condition for safe shooting. And, your primary intent is to have a shooter more so than a collector item. I realize adding the liner dramatically decreases the historical significance and pure collector value. And maybe I'm considered just the lunatic fringe of interest in these guns. LOL

I have others in my collection that I would not think of altering in this way.
This Tufek rifle was a good candidate to make in to a shooter. In it's original state, it had only minor collector value. And the Mid-East type guns are by no means rare, having been made virtually unchanged for some 200+ years. Yes, there is a big difference between restoration and altering/rebuilding. So I'm careful when picking a gun to be a shooter. Hope this sort of makes sense? And thanks again for your correspondence. Rick.
