Army & Navy C.S.L London 16ga double barrel shotgun

A very good condition, bespoke, 16ga side by side, Damascus barrelled, engraved shotgun, I believe was manufactured around 1873. Army & Navy CSL London brand. Company is still in existence. Tight lockup, and fully functional. No rust to speak of, but beautiful patina. Action is smooth. There are only 3 issues with the firearm; the buttplate is missing, there is a Crack on the left side of the buttstock at the grip and it looks like there was a small dent that was attempted repaired on the muzzle of the left barrel which left a tiny crack at the repair. Fully shootable however.  Shooting with the correct HANDLOADED, BLACKPOWDER cartridges only. PAL required, however an RCMP antique letter can be arranged.
