I bet that there is a JB on the barrels/action.
Jules Bury did most everything for Christophe.
Mahillon on the other hand mostly sourced from Francotte.
Nice find!
WC-
Unfortunately it is not stamped "JB" as my three other L Christophe guns are stamped. The barrels bear some of the same exact marking and the ribs are identical to my Jules Bury made DR so I believe the same maker did the barreis, but at this point it is not a provable fact Jules Bury made this gun. Nor are there any other maker's mark to determine the barrel maker. (No JF for Falla)
That said it is a quality gun that should provide good service, I have done a base set of cartridges and should get to shoot it next week if I can make it to the range
