Very unusual M40 souvenir indeed!!
Came across this on the worlds most popular auction site.The selller says it is a trophy helmet brought back from Italy.The outside has been painted "Gothic Line San Pietro-Hill-810 3rdBn. 133rd. Inf. Regt. 34TH. "Red Bull" Inf Div. I dont know what to make of it to be honest, just thought it was very interesting.Very rare if its not a fake. I have done a little bit of research and The 34th "Red Bull" Infantry Division did fight on the Gothic Line in Italy 1944….
