Mike:

Here's a little info at Littlegun's site: http://www.littlegun.be/arme%20francaise...anchar%20gb.htm . Houllier-Blanchar, or their heirs and assigns, sourced Belgium for this example. There may be initials or a stamp that give a clue as to the maker. The "65" notes the chamber length in mm and 20.5 is the diameter just forward of the rim also in mm. By the way Houllier is noted as being the gunmaker to have fully developed the pinfire cartridge in circa 1846.

Kind Regards,

Raimey
