The Crossroads of the Aether
A fine fellow by the name of Richard Cherry has crafted a marvellous paper craft kit that is free for the download.
It is a PDF file that when printed, provides the colorful graphics and instructions to make a model steampunk aircraft with a 24" wingspand.
Good luck and here is the link: http://siriusartworks.deviantart.com/art/Aero-Carriage-Paper-Model-...
If you download and assemble it, be sure to drop Mr. Cherry a thank you!
