Mystery Socket Bayonet

[Aragorn243]

1816 bayonets are not in Kiesling for some reason, but he does have a fencing bayonet in there made from one so that's what gave me the idea that's what it is and after further research, the dimensions all seem to fit, the 9-inch blood groove, socket length and overall length are correct. Visually it looks the same and the T groove is only on them and a Belgian bayonet that otherwise isn't close. I only paid $45 for it so I got a decent deal if that's what it is.
