Nice degen.

I believe it's a Hessen Beamten-Degen for public officials.

The cypher on the clamshell probably indicates the House of Hesse, rulers of the state. The Hessen "court swords" I've seen, even for lower officials, usually show a rampant lion in this shield.

The metal scabbard, if original, is a nice variation and possibly a replacement for the relatively fragile leather scabbard normally found on this type of degen.

Hope this helps.
