I'm late weighing in on this but it seems to have drifted off into squirrel hunting anyhow.
I recently had a J. Brown "fusil" in my shop for work. Not repair, but to correct a build fault which I found down right shocking.
The forged steel triggerguard had a twist in it which would not permit it to set flat against the wood. On the right side the guard, right at the pin lug, stood 3/16" above the wood. That's no exaggeration nor typo, it was a full 3/16" of the pin lug showing on one side. My first guess on examining the gun was that it was someone's first build. That before I saw "J.Brown" on the top flat.
There were lots of other corners cut. The barrel, as TG has said was untapered in the octagon section and that did indeed look clunky. He also had omitted and molding fore and aft of the lock panels. There was no molding around the tang either, all making a "plain" gun extra plain.
But the triggerguard was the shocker and the only thing I could fix.
As to why anyone would send a gun out with such a painfully obvious defect I can only come up with one reason, "he didn't care."
I don't knock another person's work, my own is far from perfect, but I would advise forum members to be aware that if you buy a J. Brown gun you won't know what you're getting until you get it. :shake:
