M40 beaded "Windhund" helmet

[Syd]

What can be said about this M40 beaded helmet?
It is not mine, but belong to our local museum. They don't know much about it, so I thought I'll try asking here.
Can it be an MP helmet?

The liner looks strange, and someone did suggest it was a Danish liner. Only if I compare to the 3 different Danish M/23 liners I have, none of them looks anything like this one.

PS. The white writing is a museum number.

Very curious item, not seen a helmet so marked before. Perhaps it is a Finnish rather than German Mod 1940.

Looks like post war messed with beaded.

I think that was for a member of the Dachshund racing team staff, not 116. PD.
