Mauser Bayonet?

[PerversPépère]

Hello!
One of my friends found what looks like an old Mauser bayonet.
It has two marks on it: W.K.O. and
a number: 7721
What is it? any hints?

PP.

German WW2 K98 bayonet, the code is likely WKC. May be a year on the spine. Issued with a matching scabbard. Nice blade!

Yep, Joe's got it. That is a later war bayonet with the bakelite grips, the early ones are wood.
