It's a very old german leather firefighter helmet (very likely pre-1933 - that's when the well known german "Stahlhelm" shape also got introduced to FF helmets) - the front says "Gott zur Ehr dem Nächsten zur Wehr" which is the german firefighter slogan.

Interesting. I wonder how to figure out if it’s real

I don't know if it's real but it looks like [this](https://veryimportantlot.com/de/lot/view/hessen-feuerwehr-helm-175581) firefighter helmet.

That's fucking cool, that's what that is!!

It seems to be maybe a military or fire fighter helmet. Is it real?

What is this?
