Steve,, the helmet is WWII but not sure from where,,when Tommy was trying to drill the holes to mount the Grenade/Nut set up and the 50 Cal clips, it broke 2 or 3 drill bits,,, He ended up using a plasma cutter to put a hole in that hard brain bucket.
It I decide not to run it for long,,, I may take it out back and see how it holds up to a 9mm, .45cal and a .308 !!!
Naw just kidding,, it looks cool, but with my Team Push/Tow Truck motif, I may add a Super Charger or Gasser hat to it in place of the WWII Lid...
Still working on the lettering/graphics !! Man my mind is warped... LOL
