I agree with Sandy on this fully. A very nice helmet, makers stamp is there, A Wunderlich Berlin, date stamp is there, 1913, Bekleidungsamt stamp is readable and present. And it is unit marked as well IR 152. And the interior of it looks minty, even the drawstring is present. Chinstrap and kokarden are originals. There is only a little damage to the top of the spike, but you see that often. This is caused by somebody dropping the helmet on it's spike.
