Courtesy of Diggory Haddoke's Vintage Gun Journal. Some interesting insights for the layman. Blacking is indeed the last step. Worth a look. There is a second video on action making. Will search for that one.

Nothing about who made the blanks or who originally bored the tubes. I'd assume that in London by 1890, Liege was the source of the blanks and perhaps even the preliminary boring.
