Regarding the origins of the term mark I said nothing. I mentioned Mark Twain because of the use of mark to mean a boundary where one thing ended and another began. It is either of Scandinavian origin or old Latin as in marque. But it is many centuries old.
The British used it more than many others in the last two centuries for firearms.
