I think we all are unofficially tracking where these amazing models ended up. It connects the dots and creates a continuity I find fascination and reckon we all do too.
Every once in a while you get to see something surface you never thought you would, like Gold Leader, or Vader's Wingman, the remains of Triangles, and even some crazier stuff from the first days of ILM in December of 75/Winter of 76. I'd love to see it all documented, and put out there for fandom at large, and it looks like a lot of the photos that surfaced over the past ten years will be with the new Japanese Chronicles, which is really cool!
While we do not know the current status of Red Jammer, we do know it's in the official collection and is treated like a museum piece. That's good to know!
