Well, I can certainly see the lineage from my MFX to yours. The helmet looks like it has "evolved" for lack of a better term. Funny how the shoulder bells have not. Interesting. My helmet cap and back were also in two pieces and your faceplate looks sharper. Also the older "ears" were in two pieces. He used some kind of glossy HIPS as well, very thick. Is yours glossy HIPS or painted? Thanks for sharing.
Oh, and your helmet building skills are just plain better than mine. Nicely done.
