Picture above is a finish 1:1 scale Stahlhelm helmet by riechel_juri from Russia. Looks like a real one isn’t it ? Suitable for cosplay and Halloween..
Paper craft templates made by rocketman from deviantart, Stahlhelm is the most famous helmet during Germany’s Reich-era.
It was designed by Dr. Friedrich based on countless research on head wounds sustained by Germany’s army.
The helm is actually based on Sallet helmet back in the 15th century. So if you’re a creative person you could just designed something else on top of Stahlhelm, change it into whatever logo you like.
Make it into a Full Metal Alchemist ? I think it’s a great idea if you don’t like the SS logo.
