The Steel Fox prototype cover

I don't know if I'll actually write out Grandpa Jim's story, but if I do, this may be the title for it. It deals with World War II and a Top Secret Allied forces special ops division sent in to capture/destroy advanced Nazi technology. In this story, Jim will be kind of a combination of Wolfenstein's BJ Blazkowicz, Marvel's Steve Rodgers/Captain America and real life war heroes Audie Murphy and John Hart (My Grandpa!).
