One Factory and two Dymerski Falcons on a kitchen table.
The 32" miniature never had landing gear attached to it. The bays do not open. The model was built for all of the aerial acrobatics the Falcon had to perform in ESB. The Falcon that lands on Cloud City (after the inital CG model approach in the Special Editions) is the 5 footer with the added landing gear footwells that were missing in A New Hope.
The 5 footer was again used for the close-ups in the asteroid worm's belly, but the 32" was used for the close-ups when the ship was hanging from the underside of the medical frigate at the movie's end.
The 32" is used throughout Jedi and appears in A New Hope Special Edition where it depicts the Falcon in all of the matte paintings of her parked onboard the Death Star.
Hope that helps clear up some things.
