A wild guess as i know little about imperial German units, 153rd (8th Thuringian) Infantry formed in 1897!...
It's a wasted trip baby. Nobody said nothing about locking horns with no Tigers.
I'm Spartacus, not really i'm Paul!...
nice bayonet and pics.
153.R.3.196 = 153 Infantry Regiment (8. Thüringisches Infanterie-Regt. Nr.153
(Altenburg, III Bn Merseburg) IV Armee Korps), 3rd company, piece number 196
The M71/84 appears to from the 3rd Bavarian Reserve Regiment, 2nd company, piece number 181. The scabbard looks to have been passed around a little, seeing service with different regiments, 6th Regiment (Grenadier-Regt. Graf Kleist von Nollendorf (1.Westpreußisches) Nr.6 (Posen) V Armee Korps) 9th company, piece number 217. Then with the 83rd Regiment (Infanterie-Regt. von Wittich (3.Kurhessisches) Nr.83 (Cassel; III Bn Arolsen) XI Armee Korps), 12th company, piece 51.
This is the conversion of the short 1871 Mauser knife-bayonet, which was then deployed on the model 84 Mauser rifle with tube magazine, and finally modified between 1900 and 1905 to use on the Mauser 98 rifle.
They were made utilizing blades of the M71/84 knife-bayonet and were designated M84/98-(1st pattern).The scabbard, though of the correct type, has mismatching regimental marks.
