Here's the Revell B-2 kit I built. http://fantastic-plastic.com/REVELL%20B-2%20HIGH%20TECHNOLOGY%20BOMBER%20PAGE.htm
I'm still looking for the roundish UFO-type model I built back then. I may be mistaken on the Aurora name, but I could swear the thing was a round flying saucer with stealth-type exterior paint. Don't remember if it was Testor's or Revell, or some other brand.
