Hello knowledgeable collector!
I collect german dagger but I like spiked helmet too.
I know this helmet since many years. It's in an old french collection in my area.
I can buy it now but I've any idea about originality.
For the price my guess is in the 6000/7000$ range if original?
Attached close up of the front insignia. I've do photos of the inside too & you can the the 2 totenkopf below prongs.
With these photos, are the insignia good or bad? Thanks a lot for your time.
