Dornier 728 AEW

Does anyone have any pictures of the Fairchild-Dornier/Northrop Grumman 728 AEW, which was to use the AN/APS-145 type radar of the Hawkeye? It was to be a cheap alternative to the Wedgetail, which, ironically, is also partly a Northrop Grumman product! Any information would be appreciated, as I can only find articles, but no pictures!
