A mysterious M17 steel helmet

[Adler 1]

Not so long ago, I was able to acquire this strange helmet. It's an M17, because of the metal liner band and yet with the M91 lugs for the (missing) chinstrap. There's no makers mark or size visible...
The color appears to be period, but it's a strange brownish glossy paint. The helmet itself looks German, not Austrian, but yet the color does look more Austrian...
Maybe you gentlemen can point out what this might be?

How big is it?
It looks oddly small from the photos.
If it is not a kid´s helmet, I lean towards pw reissue paint.
Maybe Czech?

Sorry guys, I couldn't resist to this little joke :-" ... This also proves that making conclusions based on pictures alone are not always this easy...
Anyway, here's the little critter together with his big brother...

Of course not... It's just funny to see this little one together with his big brother...
