I found this site looking for a Rocketeer helmet: http://groonesworld.com/
That and other helmets, original spacecraft, cars, and a couple buildings, free DLs. The designer calls them "low poly" but they look cool to me. I know it's bad form to post direct links to models, so be warned there are some DL-able models on the homepage; others you have to click "Papercraft" at the top of the page. Mark L. Fergerson --
