It's a one off scratchbuild from a guy in Spain. People have emailed him about it and he won't give out the secret.

Anything that can be made once can be made twice (though it may be too late for this project).

Maybe if you did e-mail him and took a nice little Spanish (or Brazilian) holiday you could end up with some footage that might be useful for ESB:R and ROTJ:R.

Do we have any originaltrilogy.com agents in the field who could shoot the material for you?

I'm surprised (what with the success of similar robotic toys on the market) that Lucas hasn't got a company like Wowwee to make a model like this one already.
