I think the screenused animatronic miniature is also part of Burns' collection. A rubber/foam miniature puppet is in another private collection - supposedly the one that fell into the air shaft together with the miniature loader.
It was in the upstairs Lightstorm conference room during Titanic filming. It was pretty incredible to see in person. The miniature power loader was also in there.
hi
I used to own the floppy Original Queen Rodpuppet from "Aliens". It was the one falling down the shaft with the powerloader. The other mechanical Queen puppet is still at Bob Burns place. Unfortunately everytime i see a newer Picture it Looks like it's falling more and more apart..Mine was in pretty good shape. I've sold mine many years ago to a friend of mine for $ 15'000.-- and he had it fully restored and built a nice Display for it and sold it at "Profiles in History" around $ 30'000.-- at auction as far as i remember. there was a third one... but i never heard where that one did go.
The one in Cameron's Office and Winston's Office were always copies made by Winston (not the Screen-used puppet). If that helps.. Sincerely Roman
