I was wondering if anyone knows what this helmet might be.
I had a look in Mick Prodger's book and couldn't find it anywhere. It has a blue flannel lining similar to that used on a lot of Soviet gear.
My best guess is that it might be a post war Soviet training/glider helmet. It has no tag inside, just some inked on numbers
This wartime Soviet photo is the closest to it that I can find, but the ear flap looks a lot wider.
