Up for your consideration is an Original German M40 that was used by Finland. The shell is marked EF66 and Lot number 133 (looks like that to me but it is heavily stamped). The helmet was used by Finland and has had a Finnish liner and chinstrap installed. This helmet has had extra holes drilled in the side to accommodate the Finnish chinstrap. The helmet was repainted by Finland as well. The helmet shell is 100% original. Also, the 3 pad liner allows me to wear this helmet and I wear a 61. Thanks so much for looking!
