A close friend bought a mixed parts French musket( possibly a revolutionary war gun built from French parts) years ago, that has a musket lock that looks like a 1763 Charleville, but has a goose neck cock, and a brass pan. The lock looked older than 1763 to me, and was marked with a name that was either the builder, or the armory it was built at. The engraving was in rough shape but the name was Mabeug or something similar.
