First off, congrats on your acquisition. When this came around the first time and a few key people missed it, I thought it would never see the light of day again. For once, it is really nice to be wrong.
As much as I am all about accuracy and as much as having a casting off a piece like this might inspire me to actually work on a Zam costume for Mirax, I have to agree with MonCal... I think there is serious potential for damaging the piece if anyone but a pro cast it up... and even then, there is always some level of risk involved.
It is a truly killer piece and thank for for sharing the pics!
