I'd suggest this. If you find it, it will be a collector's item that cost $ 125 eleven years ago when new.
It was sold by a small company called Starship Modeller. Their phone number is at the bottom of the instruction sheet, which you can download from Scalemates. If they are still open, you might call them.
If you were still interested in the subject, a decent model could be scratchbuilt using the drawings in the instructions. Buy an AR 234 or HO-229 kit on eBay (they are cheap) for the decals, cockpit, landing gear, guns etc.
Other articles suggest that there's a toy of the same, but I couldn't find one online.
