Early fluted spike bayonet?

[browningautorifle]

The one I had was marked SM very faint in a script type of lettering. The butt was blued and the blade was perfect silver. The whole thing was flawless. This is typical of the early bayonets as the later ones degraded in workmanship. many today have been allowed to rust in some far off armory and that might explain the paint. There ARE lots of fakes being reproduced by milling the spike to spec. The butt will likely be rougher than the original.
