The cufftitle was the only identifying insignia. In addition to the SS-Kriegsberichter cufftitle, the Waffen-SS also had a cufftitle for their propaganda unit: "Kurt Eggers", named in December 1943 in honour of the editor-in-chief of "Das Schwarze Korps".
The SS-Kriegsberichter cufftitle continued to be worn by many SS-KB and quite a few SS-KB wore the cufftitle with their divisional or regimental cufftitles, although this was strictly-speaking against the regulations.
As for the Luftwaffe, they also had a propaganda unit with its own "Kriegsberichter" cufftitle, as did the Heer and the KM. In addition, the Luftwaffe had a small sub-unit of para-trained LW-KB. I have some photos somewhere which I will dig out and scan when I have a moment. There were also para-trained SS-KB, the most notable being Adolf Kunzmann, attached to SS-Fallschirmjäger-Btl 500.
If you're doing an impression or a mannequin, you'll need a cufftitle plus a period camera of the types used and maybe even a portable typewriter. They also used pigeons to carry stop press dispatches. Other than that, they wore bog standard field kit. Ranks began at corporal.
