hi ritterkruz
my name is andy militarynut i have had several chicken wire german helmets over the past fifty years in this great hobby i would like to give you my opinion on your chicken wire m-40 helmet from what i can see the wire appears to have been on this helmet for ever also you are correct in saying that its american chicken wire we did export goods to germany and all over the world also england dealt with the germans to get supplys but however in all the chicken wired german helmets that i sold i all weays got a song n dance when sold every body has an opinion even a a.h. but all in all when you sell it you will get another opinion as to why its not right i hope you agree god bless have a great day andy militarynut
