Ken, it's a rifle I've been working on and hope to be able to post it in the near future,,, not a southern gun though, just an old PA gun.
I did more looking today and took off the trigger guard and trigger plate. I was going to take pics, but the batteries are dead again,, getting old I guess, like me!
On the trigger guard it looks like it's welded, or at least has a joint where the grip rail meets the rear of the trigger loop, like I mentioned before. Other than that joint, I don't see any other obvious spots. The two TG extensions where they fit to the wood looks like it has a few hammer marks in it, but for the most part is just covered with fairly course file marks, those like you'd see on the bottom flats of a barrel.
On the top of the grip rail is a long line like an inclusion, or a fold, in the iron.
The trigger plate has several hammer marks on the inside flats.
I looked closely at the butt plate, and can see where it was welded. The tang or return piece overlaps the butt plate piece, and I can see a light line on the butt plate piece where they were joined. I was going to take it off, but the screw in the butt plate won't budge so I left well enough alone.
As Carper suggests, with an unsigned barrel, whether it's the original barrel or not, or a Lawing, can only remain unknown. The barrel matches in finish with the rest of the iron parts, and fits the forearm inlet perfectly is about all I can say.
I did clean the bore though. After a brass brush, some hoppe's, and a bunch of patches the bore came out pretty clean and feels pretty smooth inside. I don't generally advocate shooting old guns, but I'd guess this one would be shootable! I checked the bore size with a .360 ball I have for another gun, and it's too large for this one, so is something less than a 36 cal.
And no, this one isn't going to get away,, not a whit of buyers remorse here!
