I collect German imperial bayonets and have a few of these interesting knives, there are practically endless variations as nearly every German state had different variants of knives and bayonets
If you look at faschinemessers you will see most have no fullers as per your blade.
Parade bayonets were also very common in late 1800s in Germany and these generally did not have any locking mechanism
Ps happy Christmas to you and all
