Not called spike! In German: Haarbusch "Trichter" (funnel)
Looks like Yack hair (For officers). OR would have the horsehair Haarbusch.
Like this piece.
Do you mind to post a picture of the other side of the detached Haarbusch (leather disc)? Thank you!
This part is a translation from the French Uniformes HS 31:
......
-The Busch or parade-hair (or feather)-plume.
The Busch or plume is an ornament worn on top of the headdress to replace the spike/Spitze or ball/Kugel top. -Worn at Parades only; by those Regiments that were entitled to; on the Mod 1842 to Mod 1895 helmets. The spike/ball top is unscrewed; the Trichter with the Busch is then screwed on. The top of the Mod 1915 helmet is detachable by the bayonet style lug system and therefore cannot be unscrewed. The Mod 1915 helmet is therefore not equipped with the parade plume. The Busch for the Mannsch and Unteroffiziere/NCO’s is composed of horsehair and called Haarbusch. Called Buffelhaarbusch for the officers; generally composed of yackhair; (rarely of Buffalo hair); giving more volume to the hairbush. General Officers: Busch composed of plumes (Federbusch). The hairbush’s are black; white or red according to the Regiment or Battalion. Red for all Spielleute (bandsmen). but...Red for Bavarian Artillery as well !
-The plume/Busch is composed of three parts:
#1-Metal cone-shaped tube; called the Trichter/”funnel” that lodges/screws onto the spikes/balls base, holding #2- the parade plume: hair (or feathers); connected together and sewn between two leather discs.
Finally, this plume is screwed on top of the Trichter by means of:
#3-a metal rosette with a welded-on screw rod.
-The Trichter is a brass or german silver tube-smooth; sometimes fluted for the officers-when the helmets spike is fluted. The Trichter base lodges a screw rod to allow fastening into the spike base of the helmet. The top of the Trichter ends on a round disc with a central threaded hole for holding the rosette with its welded-on screw rod.
-This rosette is brass for Mannschaften and Officers. The rosette for the Senior Non-Commissioned Officers is: white-metal with the black and the red Busch; painted black with the white Busch. This color code is not dependent on the color of the helmets metal fittings (yellow or white).
-Through aging, the horsehair brittle and it falls off. Nowadays these Mannschaften horsehair Haarbüsche are therefore particularly rarely found complete and in good shape...
