Asian Occupation Brigade Officers Pickelhaube. German Model M1895 Officers pickelhaube with East Asian Brigade heraldic Reichsadler.
The East Asian Expeditionary Corps ("Ostasiatische Expeditionskorps") was a large force about 15,000 in total made up of volunteers from the regular German army reformed into new units for service in China in the Summer of 1900. The East Asian Expeditionary Corps were sent to China in 1900 with the Pickelhauben of their home units. In February 1901 new uniforms in field grey were authorised for the East Asian Expeditionary Corps (and its later successors, the East Asian Occupation Brigade and East Asian Detachment). These uniforms included a new universal Pickelhaube bearing a heraldic Reichsadler.
A very rare example here.
