Daryl,
Yes it does. The brothers seem very intent on communicating the importance of those gauges. They talk about them quite a bit and went so far as to have them illustrated as you point out.
Language becomes confusing as I dig further back. They seem to use "Catalan" as their term damascus barrels. Others site this book and use Catalan to denote the locking mechanism. Certainly when referring to Eibar, Catalan is used for their (Spanish) enhanced flintlock. Actually the term Misquelet is used to describe the type of firearm being produced by some.
I am still not clear at what point the Italians come into this picture. They were certainly a player at this early stage. Just can't find enough documentation yet. There is a book, "
Brescian Firearms: From Matchlock to Flintlock - A Compendium of Names, Marks & Works Together with an Attempt at Classification" by Nolfo de Carpegne that may be of some help.
I just have to be careful to not get caught up by lock development.
Pete
