A very important and rare NASA produced model. Three models were made with a white central booster tank and given to three major news networks (ABC, NBC, and CBS ) for display during shuttle launch programs. Three additional, with orange booster tanks were retained by NASA for internal use. This is only one of of two in private hands. Acquired by an engineer in spring of 1997 in auction it remained in his personal collection until his passing. Auction catalog provenance listing of model is provided. In great overall condition. A few nicks and chips are noted in photos but not distracting. Booster cones have chipping on the back of rocket—the non display side. Very large scale 1/48 measuring 20” x 50” x 10” and mounted on a heavy oak base with engraved placard.
