I found this and looks to me that the wappen is a dragon
text with the photo ( translated from french to english ) from L'illustration 24 june 1905
Seven Chinese officers, having already spent four years at the Wou-Chang military academy, have just taken up service in Germany. Three of them were attached to the field artillery corps, garrisoned at Wesel, three others to a regiment of hussars, at Dusseldorf, and the last served in engineering, at Deutz.
A photograph, all picturesque and documentary, brought them together in a group of a very suggestive aspect. Under their German uniforms, they have really beautiful dress and martial air, these sons of the Celestial Empire, current ornament of the German army, hope of the Chinese army, and if, by the type, they recall the Japanese officers , their size, greater than that of the Japanese, gives them perhaps more military presence.
So, here are the Yellow people from China who, like the Yellow people from Japan, learn closely about Western things and come to learn in Europe the art of resisting Europeans and, if necessary, fighting them. "The Midi goes up", they said in our house as a joke; one could say more seriously today: "The Far East is expanding".
Thanks for the posting of the photo. That's interesting. What I asking about would be an actual German unit. One of the helmet facebook groups has a Busby -enlisted, ersatz type marked for 1ORR BAO. It is my understanding that the 1 East Rider Regiment wore pickelhaube and was a JzP regiment.
