A little over 40 yrs ago I got an identical kind of barrel from Dixie, .36 cal. x 13/16, but it was bent in three places and the bore was out of line with the exterior of the barrel. There's a picture for you.
One thing and another, I wasn't in one place long enough to return it and expect to be there when it came back. Being young and not knowing when to throw in the towel, I clamped it on the workbench and, one by one, worked out the kinks. Being a mild steel, it wasn't an insurmountable task. I designated the end of the barrel with the bore in the center as the muzzle end. The end that was bored off center became the breech end - I figured it mattered less where the bullet started that where it exited.
By gosh, it ended up shooting pretty well, but it's the kind of thing a younger person does. Nowadays I'd return it or scrap it, and get on with life.
