First I've heard of this one, but there are several rooms roughly like this in SF. You never hear about them, there are no credits to be found, but there is ghear. And ggghhheeeearrr. And GEAR!
Why do you think all those vintage prices have gone so crazy? It's all picked up by collectors. Commercial studios can't afford that stuff anymore...what they usually have is what's left over from their early days, or stuff collectors have parked with them.
I have no problem with people creating scarcities in the vintage market...it means there's demand for modern products which keeps that art alive, and funding for maintenance to preserve the legacy.
