This is the scarce "Hirschfanger" Jager version of the Imperial German Infanterie-Gewehr Model 1871 Rifle Bayonet; it is very similar to the privately purchased German Model 1871 Infantry "Walking Out" Dress Bayonet variants.
The hilt is iron (steel) construction with pressed-leather grips, steel crossguard, reversed quillons (upper quillon contains the muzzle-ring), teardrop lower finial with "cock's comb" upper finial.
They can be found in several variations, some with sawbacks.
These bayonets were produced - with variations - from 1871 into WWI.

Scabbards are brass-mounted or steel-mounted black leather.
