I didn't miss them, I've omitted them, since it seems they're destined for upcoming episodes. But there's things like the fabric covered biplane that looks intriguing. There's also the Tomcat that was posted as a contest on the facebook page, but nothing was ever published about it, unless I missed that.
Of course, this is all off topic, yet on topic, since the title is Chad's basement, and these are items in that basement.
