Check out this article at RetroMechanix.com on the CH-64 "Chow Hund," an American anti-aircraft missile study designed by captured German engineers under USAAF supervision in late 1945:



This four page article features 8 high resolution images, including detailed schematics of the missile. One of the engineers involved in the project, Dr. Gerhard Braun, was a key figure in the development of the Hecht and Feuerlilie anti-aircraft rockets at LFA Braunschweig during WW II. Would make an interesting and relatively simple scratchbuilding project!
