Turtle helmet Mk III(1)

Here I'm planning to do Mk III turtle helmet that someone asks me to do; I give it a try now. This helmet liner is difficult more than I think but earn an experience is better than nothing.

I collected copper and aluminum for the liner that had been trying these 2 materials which is the best for the liner.The thin copper needs to solder also not strong enough;The aluminum strong enough and needs punching holes for eyelets to assemble them, the result coming very well when the liner structure shown.The leatherette for lining then glue on the liner ,over the edge parts are folding them out then glue it.
