After 1900, I believe William Ford has the correct term for the effort being performed - barrel borer:
And he was one of the best.
I found the reference I was thinking about regarding London barrel makers/forgers(pattern welded only I'm sure) and it was the Fullerd family of William & Thomas Fullerd of Clerkenwell - Middlesex. William expired in 1830 but had a son named William(1816-1874?) which I assume continued with his Uncle Thomas for time. Some give 1844 as the last of the pattern welded tube effort by the boys Fullerd/Fullard but as talented as William, Sr. was on big bore tubes, surely he passed on some expertise to William, Jr.
Kind Regards,
