I believe I edited it now to read "FULL SCALE"...if it's not showing up that way, please let me know what I need to do to stop the confusion.
I apologize to everyone who's dreams were dashed...
To the best of my knowledge (which is pretty insignificant in comparison to the brain trust that appears to make up this board), it was scrapped and rebuilt for ESB. The original blueprints of the Falcon in the Archives have two title blocks: One that says "The Star Wars" (for ANH) and then another one titled "Empire Strikes Back" for "Chapter II Productions". It appears they simply took the original blueprints, retitled them, perhaps made notes where necessary, and then used them again for ESB. Of course, new ones were drawn for sets/parts created specifically for ESB. And, you'll be happy to know, they all appear to exist.
