Hi Ryan,
No, as is my usual stance with these pieces of history, I will do nothing to it. To me it is more valuable like this...as it was during the war. I am satisfied that this is a previous SS helmet that was re-issued to the Wehrmacht/Heer after the Battle of France. I'm not sure if any further info on the name could be uncovered without a unit or service number associated with it. As I mentioned above, there were two SS soldiers named Otto Schumann who were killed in May of 1940. I strongly suspect that one of them was the original owner but it is impossible to be sure.
