When I purchased this helmet I had a couple of Pickelhaubes nothing to special and then I came across this, back in the 1980's there were not so many detailed books on the subject and I certainly didn't have a computer (or a wife & children!!!). The helmet is stamped inside C F Junker 1913. Recently I asked the group for information regarding the types of lining for the inside peak and neck guard. (Thankyou to those who replied). As can be seen this is the blackened type.
