Wow, that looks mad! the basic shell reminds me of the British para/armoured/dispatch riders helmet with some zanny flanges added, the best guess is that its a wacky film prop?
I have seen one of these recently, I can't remember what it was or where it was that I saw it. Looks like it has the shame basic shape of a pickelhaube. I'm eager to find out what it is.
The liner and shape remind me of a haube also, I'm intrigued.
My first guess would be a Theatre Prop...
I first thought of a Picklhaube (or however it's spelled) that's been stripped down.
Russian fire brigade helmet.

Thanks to everyone for your help. I've finally been able to identify it as a Russian fire/civil defense helmet. It's actually quoted as being one of the most rare helmets ever produced by the USSR. It's included in a book, and I'm attaching a link to it below. If anyone is interested, I'll be posting it on ebay within a week. Thanks again! Russian Helmets, by Clawson, rare civil defense
