My M15 purchased a coiuple of years ago while visiting Tony. This set of pics will serve as a "before" visual of the helmet. Not much restoration is needed, restitch the rear visor and fix the sunken top of the shell. I probably will fill in the missing shellac areas as well. This helmet is marked BAX18 which is the correct Army Korps for this Regt. My JR 115 helmet has similar markings, no Regt number just the Army Korps which uses the arabic number 18 rather than the usual Roman numeral. I would think that this was done due to the amount of space that BAX XVIII would require on a rear visor. Note also, the use of brass M91 posts which is interesting and the presence of chalk/mud deposites on the wappen.
