That's a small "desktop" 3-axis mill made by Sherline. (http://www.sherline.com/
They're reasonable-quality machines, and quite affordable (although like all machine tools, you'll wind up spending twice the cost of the machine, for tools and fixtures and vises) but they're pretty small. That piece, I believe, is an A-arm for an RC car, and thus only a couple inches on a side.
Yes, people have milled 'Cocker bodies with Sherlines, but the machine simply doesn't have a lot of power- you have to take a bunch of light cuts with small bits.
If you're just getting started, and not sure if you really want to spend the coin on "real" machines, or you're just doing hobbywork, they're not bad, and Sherline has great supplies of parts, accessories and tools.
But if you're looking to do some serious munching or, say, make a paintgun body from scratch, the machine is just far too limited in size, power and rigidity.
