WW2 or post war Helmet?

[Luxembourg]

If I'm looking at the photos correctly the two "bald" spots are on either side.....if so, it is due to Helmet Stacking, the bails of the helmet on top rubbed the texture off of the next helmet and then later, the helmet was re-painted. This is quite common to see.

Thanks for the information!:-)
Under the paint is a little bit of the original, so I left it like it is
