Hi, looks like a fibre glass post war helmet to me. Leon.

It's a wasted trip baby. Nobody said nothing about locking horns with no Tigers.
I'm Spartacus, not really i'm Paul!...
Movie prop maybe .
That's what I was thinking. Made for a movie but lean toward some type of static display (can't see this stay on an actors head lol....)
My greatest fear is that one day I will die and my wife will sell my guns for what I told her I paid for them

I would guess that a lot of this stuff came from a prop house, your father may have bought the lot because a couple were good. Most of us don't throw the bad stuff, we just put in another box.
You don't have an easy job sorting this stuff out, I would say the stuff that gets good reviews put to one side and for further investigation and decide what you want to do, stuff like this throw it on ebay with no reserve and get what you can for it. I purged the junk from my collection a few years ago on ebay, as a seller I thought it worked well and you define when it gets sold, just don't miss represent it.
