Here's something you don't see everyday, a Polizei Seitengewehr from Baden. The pommel is curved over to comply with the Treaty of Versailles requirement of no bayonets that were able to be attached to a rifle.

I've owned these with the short blade (about 17") and the long blade (22" + or - from memory), this is the shorter one with a 3R period maker mark. I've owned it maybe 20 years and it took me almost as long to find the right knot in the right condition.
