At the very bottom are some new MD-83 throttle quadrants as well as some from a new 737-300 teardown. I just got my MD-83 throttle quadrant and it's not quite so well completed, so I'm a touch jealous, but there are a couple. Mine is nearly complete in American Airlines anyways so that'd leave me with a bunch of excess "crap" to try to offload, and it'd all be the heavy part.
