OK - it arrived this morning. I knew I probably wasn't getting a quality item - you get what you pay for (£21 - about $40 or less). So pics attached. The neck guard makes it impossible to look up where it is. Dome is one piece, spun I'd say, looking at the hole in the centre. Some kind of (chrome?) plate on exterior - that'll come off (best method?), looks like a zinc paint on interior, tatty faux leather liner (destined for trash) Stand is some kind of LOTR stand - wobbly, but repairable. Everything is rivetted to the dome. All appears to be about 18 guage. Rivetting is fairly loose so should be easy to dismantle "Frankenhelm".
Now - I am going to create something half-way decent out of this, even if it is a LARP/fantasy piece. I still feel with a little work there is a profit in this. The neck guard has a similar shape to the fin (cooling?

) on LOTR Uruk-hai helms. I've attached pics - so you can all laugh at my impetuousness and foolishness in buying this. Once you've finished let us rebuild it! We have the technology. I'm sure the esteemed members of this forum have the ideas as well. Look upon it as a challenge! I'm trying to raise money for a decent helm (not sure what I want, something about 450-600 AD probably, not sure why!). I reckon that this can be turned into something for the LARP market fairly easily. Thinling caps on guys & gals.
