I feel very fortunate to have its less fancy older brother, No. 14967, chambered in .500 3" BPE.

A very similar rifle, made in 1894, with fluid steel barrels and slightly less embellishment.

It's an interesting placement of the fastening screw for the locks on No. 16167. I don't recall seeing a centrally located fastening pin like that.
