This is an interpretation of an Italio-Norman spade faced phrygian helmet that I recently completed as part of a trade. It is severely modified in overall shape and design in order that it can pass inspection for SCA combat.
The skull is a 2 piece bowl that I purchased. I've dished enough of my own by now that I prefer to let someone else handle the 'grunt' work so I can spend more energy on the details.
The mail drape attached to it is one of Master Knut's welded stainless aventails. So I can't take credit for it either (beyond mounting it on the helmet anyway).
The helmet is constructed from various thicknesses of mild steel ranging from 16 gage to 10 gage depending on location and application. The brass is all recycled kick plates for doors.
The pierce work was done with a jewelers saw and needle files. The engraved lines were done with a customized cold chisel.
And despite my complete lack of photographic skill, I think this is both an impressive and intimidating shot.
