A friend who owns a gunshop went to a gunshow up on Morgantown , WV over the weekend and came back with this old piece. At first I thought it was an old civil war arm converted to shotgun.
You can see the breech open above. You pull back on the block to extract the fired case. You can see the extractor below.
Model 1857/67 “Zulu”, Fabrique d’Armes, Liege, an 1857 French muzzle loading musket converted to a 12 gauge shotgun with “Tabatiere” Snyder style breech system by the Belgians in 1867, sold surplus on the African trade and elsewhere as an affordable shotgun. Manual ejection. Walnut stock. Stamped “ZULU” on the barrel, Belgian proof marks on the breech block. Takes an obsolete 2″ shell. 34″ barrel. 52″ overall. .
