I've just finished this one for a friend. It's made of fiberglass and it's very light (about 150 gr). It was sculpted in clay and molded, and after some sanding it gets really smooth. Hope you like it!!
The paint is very rough, I did it against clock :S First I painted a silver coat as a base. When it was dry I use a very common patina called 'betun de judea' (sorry, I don't know how you call it.- is brown and you usually use it to ageing objets in handcrafts) It was washed a bit so it becomes more transparent. Then I paint again the silver. The blueish tinted look is just the reflected curtains but you can do it with a very thinned glass paint.
Thanks!! I'm glad you like it. I have made another paint version of it, more metallic look. I don't know what is the real thing color, but looking at the noble replica it was metallic brown. I like the grey one more
