Thanks for the compliments, guys.
Heya, MetalBoy. I was going to hammer out a sheet of aluminum to make the dome like I did my armor and cheekpieces, but after really studying the pics of the real helmet, a light went off in my head. It looked alot like the dome of a GI steelpot helmet. I got one and cut it up. Lemme tell you, buddy, THAT was a b!+(#, but it ultimately saved me alot of time( I had to use an angle grinder to cut that stuff).
If you're ever in a surplus store, check one of those out for your next one.
