The helmet was a m42, by which time most helmets are only single decal, therefore not SS as its on the wrong side and not luftwaffe as its the wrong shape so either Heer or Km with the former more likely simple because of numbers issued.
Whatever its just an opinion.
It is nicely preserved. What sort of ground conditions?
Hi, Jerry is spot on, it is a HEER M42 helmet. Leon.

Yep, 99% likely it's a Heer M42. I dig it. What country and region did you find it in, if you don't mind me asking?
