Dress Bayonet double marked WKC?

[DerKerl]

Just got this double marked WKC Dress Bayonet. Knights head on the obverse and three line WKC running up the blade on the reverse. All steel and never plated. Fully operational. Over 26cm blade length. Never seen one like this. Thoughts?

Another unanswered thread worth bringing to light as it shows a dress KS98 from the Weimar period and we know that from the early form of the Knight's helmet trademark and the full company name, which ceased to be used from 1930. Fairly rare example to find.

Steel handle, it possible its attachable on rifle, similar marking was used on Polizei SG, so it could be a service bayonet in form of KS98 of unknown branch of unknown small area, town location? b.r.Andy
