I found 4 complete wax prototypes and most of the original molds used to convert to resin. They are:
Sauron, Magneto (2?) with alternate smaller head, Gideon, and Four-arm. Anyone ever come across similar stuff online? I can't find anything.
(pics up soon)
Pics of the wax
That is very cool. It does look like Magneto 2 in the pictures you have.
Waxes are often destroyed in the process of making the resin molds so you don't see these often.
I would be interested to know how the person who had them ended up with them in the first place (unless you lucked onto an original sculptor).
What area are you in?
And of course - are there any more!
