Ive been having this idea for awhile, not related to the decal idea's posted above. But, I was thinking of after I chop off the "dent" portion of my mystery helmet recast, I was thinking of modifying it, and extending it, like adding a solid cylinder shape to it, but keeping the curve and dent on the top. I would mold it in resin, and countersink a magnet into the back of it. After, I would base paint the whole thing "TDH red" and then do the white highlights as you see in the top right corner of the page. Would probably write something on the side that would associate with the TDH or whatever
Anyways, just an idea
