The shotgun belongs to a friend.
Right now we know the name of the closing system (Lefaucheux).
I will try to remove the forearm and barrels with the advise of Rockdoc because right now the shotgun is at my home.
I am just a beginer regard apretiation of old firearms, but I am almost sure that the barrels are refinished because they have a perfect blueing; the woodstock have an horrendus yellowish varnish finish (done with a brush!!!), but the sidelocks are pretty much original because the CC are near to zero in the rear zone, where are in touch with the right hand, but some colors in the fron part.
I still wait for more answers from the knowledge people of this forum.
Regards,
Jose
