Vintage Metal Military Helmet Metal with Straps

Description

A vintage metal helmet with chin strap.
It has a great patina to it & looks as though maybe it was originally black.
I don't know anything about this & there are no markings that I can find.
It has seen better days. The interior is a bit rusty& the exterior has some bumps on it.
I don't know anything about this so hopefully the pictures will tell the story but fee free to ask any questions.
It measures approximately 12" long  x 11 1/4" wide x 5" tall
We typically ship by USPS Priority Mail but will be happy to ship with your preferred carrier.
Thanks for looking!!
