In addition to the -400 version Phil mentioned, there is an older Revell -100 kit that can be found in various places. I believe it was the basis of the Space Shuttle transporter set as well as the cutaway version. I've seen it in TWA (twin globe) colors (kit No. H-316), if a remember correctly. It was also released in United (kit No. H-197). There may be other versions also.
