To what extent did American pre-war custom makers use integral ribs on their barrels? What about British and European makers? I know there is a thread from 2-3 years ago asking about soldered on ribs and it's mentioned that lots of German barrels had soldered ribs. I know I've read descriptions of integral ribs on G&H rifles. But the description was from the person selling the rifle, and if well done and blued, a properly soldered rib is very hard to distinguish. Plus I also think that "integral rib" is becoming a generic term - even when it's probably soldered on. I've seen at least one auction where a very early rifle is said to have an integral rib, which I doubt was done much before WWI.
