Carcano M91/28 Barrel Band with Bayonet Lug
Original Carcano barrel band with the bayonet lug. I randomly had this in a box of parts and it took a while to figure out exactly what it was. Shows some wear but looks to be in decent shape.
After some research we are fairly certain this is for the Mod 91/28 rifle.
Most other carcano bayonet lug caps , the side screw head is recessed into the ring.
