Drake,
A good start would be the Osprey Military book entitled, "German Armoured Cars and Reconnaissance Half-Tracks 1939-1945." Or you could just borrow it from me the next time you see me. A second good source would be the 116th Panzerdivision's website:
http://www.116panzer.com/ and ask them. They reproduced one for themselves that I saw at Camp Atterbury last year.
