Nice to know, Raimey . . . but the guns discussed in this thread don't date from 1866. And the Belgians were far more involved with the gun trade outside their tiny country than were the French. Somewhere I've saved an article by the late John Brindle from Shooting Sportsman, in which he pointed out that French gunmakers never really launched a concerted effort to sell the guns they made anywhere other than France.

And your article also shows that the Belgians were into making "clunkers" (the very lowest quality), while the French were not.
