Unknown Bayonet & Scabbard; Era, Nation, Maker?

[wlwhittier]

Good morning...
This is 13 5/8" overall, in its sheath; the blade is 8 7/8" X 11/16", saber ground, an' is integral to the tang, grip & barrel-fixing feature.
The right ricasso is marked with a 'K' beneath a three-lobed crown; the scabbard is marked twice with '4072'. I can find no other marks.The release button is dual function; barrel & sheath latches. Weight, in its scabbard, is 12 ounces.

I'm ignorant about bayonets...but think it's European, late 19th C to maybe 1920. What can y'all say about this bayonet?
I'm grateful for all your comments an' suggestions. Thanks of lookin'...Warren

Thank you sincerely, Arathol!

The 1956 is a modified M1894 model, they look quite the same. The 1956 was for the M1 carbine, the 1894 for the Krag. The sheath looks like the earlier 1894 model, but parts seem to be missing still.....
