Have a a couple of old eight bore singles that I no longer require, one is an American Davenport looks like a Stevens single shot with central hammer and long top lever that extends under the thumb so no contact upon firing, used and inspected. Damascus bbl, 3 1/4" black powder magnum, full choke. Age uncertain but think between 1895 and 1900. The other is a British 10 bore ML with an 8 bore steel barrel, proof tested and re miked by my self to 6 bore provisional in the white, then 6 bore definitive so - well over proofed for 8 bore ML, any one interested?
