As themick said, it's an Austrian helmet with replaced strap.  A desirable helmet IMHO. 

A  Panzermann wears a tunic over his Black uniform, looks like the cotton summer version rather then wool no?

Thanks Jim and Steve, we were pretty blown away by this donation to say the least.    Scott

Nice original pieces out of the woodwork.  It doesn't get better than that.  Thanks for sharing!!   Steve 

Thought I should post it here too, just in case.

Thank you! They are a neat patch. Here is a poster that was sent with my trades years ago.

Yes, I posted this before I noticed your second thread, amazing!

Simply stunning! I was always fascinated by the Scandinavian Armed Forces insignia´s style. Thanks for sharing.

I just added my collection here. https://www.worldmilitariaforum.com/forums/index.php?/topic/323554-norway-collection/   Sorry don't have a translation for these.

That´s an impressive collection! Could you ID all patches´ units?

Thirty years ago in the early years of the internet, I met a man in Norway that wanted US insignia.  He was in the guard and going to college.  We couldn't send pictures so had to do it by snail mail.  These patches and insignia set in my collection still in the package they were mailed in.  Recently I found more of the obsolete ones on an auction.  So decided to get them out and show them off here. Included are some of the correspondence from Mr Lund in Norway. 

Here's my small group of obsolete patches. I love these versions.
