Interesting Marine SA dagger with gold fittings made by the marker Gebrüder Bell.    

This dagger features the motto "Alles Für Deutschland" and the maker marks on the reverse for Gebrüder Bell.  The blade does shows signs of age with some discoloration and tarnishing and significant wear over the market logo.  

The brown handle features the eagle and SA roundel with has some chipping to the glass enamel.  The gold marking fittings are clean.  The Pommel nut does show signs of being opened or tightened at some point after being refinished.  The crossguard is stamped Ha for Hansa.  

The brown annodized scabbard retains most of its finish and the fittings shine with bright gold showing slight loss to finish at the mouth and around the ring.

Most likely gold fittings were replated after 1945.
