Thank you for finding this Drew.
This is a British take on things as of April 1897, and how the folks at the Schultze powder factory perceived things. Interesting, but mainly is dealing with 2 1/2 inch British shells and a wad column from 1/2 to 5/8 inch long, nothing near as long as the wad column would be in a North American 3-inch shell. When he discusses the shell actually fitting the chamber, he shows the shell openning into the forcing cone being a bad thing, but the diagram shows the shell protruding the full length of the forcing cone, not the 1/8 inch several American manufacturers came to favor. Also, quite a short forcing cone in all his diagrams.
Would be great if we could find something like this from a North American Company, DuPont, Laflin & Rand, etc. from maybe somewhere in the 1900 to 1910 vintage.
