Helms are not my field of expertise,but I have get him from a proven supplier of ww2 equipment. Writing that is not my part of expertise not to distance my self from something or hiding, Iam writing that cos when I go on forum and read other coments about liners,models,number of holes for air. Thats definitly something I dont know, I know that for me straps are looking newer and thats probably in some point sometime someone probably do a makeover ,cos I have m1,JNA, 2 Poland helms, DDR helm, forgeting names,wz something, West german first model also, but all of them are not being looked and cared,me also holding them in my garage, Iam just an entuziastic fan of militaria,and this model I belive is for all number 1.
