I have a 1924-1927 Fabrique National d'Armes 16 ga sxs that has a screw plate over the hinge pin. You can take the pin completely out or rotate it and re-spot the set screw that is between the knuckle.



This gun also has Krupp Essen steel barrels.

L.C. Smith used a tapered hinge pin and I have only heard of a few ever being replaced.
