Actually, Grant McCune shop did the Pyro shots. The parts left over where not destroyed XWINGs, but the masters they used for casting.
John found the box when he worked for Grant, and was helping move the shop. Grant gave him what was in the box, when John expressed interest in it. The Box had the WING, engine, and Butt Plate masters.
There was one complete Gun as well. There was a fuselage, that had been partially crushed. John repaited the fuselage, and eventually aquired parts that were missing, rear hatch, gun tips etc from folks who had worked for ILM or Grant.
Those parts were the same parts loaned to ICONS. WHo modified thier castings to make sure they would never be confused with real Xwings.
Max Cervantes did those modifications, and he himself told me about it.
When MR went to make thier XWING, the same parts were loaned to them, but rather than Just remold 4 times and modiefy them, the parts were molded ONCE, then those castings sent to the factory in HK where they were scanned and modified to match the RED 5 Reference pictures.
EFX would eventually finish the effort. The Fuselage was scanned, and rebuilt in the computer. It was also corrected for shrinkage based of measures and dimensions off of HERO Ships. Then grown, and cast for production. Unfortunely, the same % of Shrinkage correction was also applied to the actual kits parts, which DIDNT need correcting as they were real parts.
Thats why the real parts are oversized.
I still feel the EFX XWING, is the most accurate reproduction out there.
Im happy to have one in my collection.
