Bad news on that front: if you read further down in his build thread (someone else asked this same question...I think I did, too, a few weeks later), you'll find that most of the files he used were by a user named AceHigh. AceHigh, for reasons unknown to me, asked the moderators to remove his files off of the site, and for people who already had copies of the files to NOT share them. It was the moderators' decision to respect his wishes in that regard. I believe some members were banned shortly afterward for not complying with AceHigh's request to not keep his files available.
Sorry about your luck. Probably the greatest loss was his files (yes, files plural) for Jorge's chaingun. Those things are incredible.
