I hadn't thought about a kit specifically; I mostly just thought it was cool.
But I may build a kit around it.
It looks like the rim and skull portion are one piece dished to have that shape, rather than having the rim welded or riveted on. The spangen bands are all one piece (a large cross, essentially). The fit and finish is on par with the sallets we ordered previously, and it's lined the same way. The rolled edges around the rim almost look like they're rolled over the edge of the leather underneath, but in actuality they just perfectly meet.
Really not bad for the price at all.
