Pre WW2 German bayonet with scabbard

A bit of a mystery to me!
This is different from the German bayonets I know, but it is made in Germany for sure.
Bayonet and scabbard are in excellent condition.
Scabbard is made of leather with metal mounts.

The bayonet it self is marked with “Weyersberg  Kirschbaum & C  Sölingen”
It has a muzzle ring what you don’t see normally with WW2 period German bayonets.
I suspect there for that this bayonet is a WW1 or even older age.
