Several sources allude to filzhelme being used on the Serbian front. These allegedly had removable spikes and numbers on a scroll instead of a normal wappen. Trichters were never used and cockades were not there. There are supposedly shields for mountain machine-gun Abteilung 211 -- 250. There are also references to an R 116 scroll and an R 22 scroll. The author has a picture of two IR31 soldiers wearing these helmets. These helmets were supposedly not used with a bayonet spike attached and some had a Foreign Legion type neck guard. I have no problem with the existence of these helmets.[xvii] However, there does seem to be a problem with their use on the Serbian front. I do not understand how IR22 or IR31was supposed to be in Serbia . Nor reserve Regiment number 22. There is one source that talks about these number plates going to reserve infantry regiments and Ersatz infantry regiments. Unfortunately there is a lot of talk about reproductions and these helmets. Recently there was one that was listed in the Kube auction. So I do not think that they're all reproductions.
