In addition to Boxpok, there were Scullin Disk (as early as 1932, in a Railway Age article - <!-- m --><a class="postlink" href="http://railroad.union.rpi.edu/article.php?article=2597">http://railroad.union.rpi.edu/article.php?article=2597</a><!-- m -->) and the Baldwin Disk - very similar to Boxpok, but with raised edges on the "spokes". Baldwin disks were contemporaries with the Boxpok. It would seem that all three came from the rapid development in the "Age of Machines" (1920s and 30s). Coincidental to their engineering advantages is that they look so cool...! Gotta love the Art Deco/Streamline/Machine Age stuff
