Packard Mill Photos/Video Footage

[David Lynch's Khaki Pants]

Please move this if this is in the wrong place, but is there any footage of The Packard Mill behind the scenes anywhere? I'm interested seeing what it looked like around/inside up close at the time of filming. Was it ever available to tour? It's one of the few filming locations I really can't find footage of from fans up close or production behind the scenes.
