From the preview:
A special Friday sneak peek for you guys. This will be our first free unlocked mini for the upcoming KS. As a small company with limited budget that produces high quality metal minis we won't be giving away a ton of models. We'll leave that to the guys who produce plastic stuff in china. But we will be rewarding our backers with some bonus stuff. This little guy is ready for action, and your Kickstarter Support.
