Grandpa's gun

[swampsavage]

The dagger is, indeed, Heer (army) although the grip is not ivory. It's a celluloid type product. It may have darkened some but may also have been colored when new. The blade should not be sharp. There were several dozen different makers of them and should have a makers mark near the hilt. They were not weapons of war and carried with dress uniforms on ceremonial occasions.
