I am thoroughly confused about an element I have come across:

Missile Launcher

I have never seen a piece quite like this.

It's unlike any Technic connector I've seen, so I doubt if that is what it's for.

The two facing holes on the sides are standard stud diameter, but the tube on the top has angled faces, and doesn't look like any standard Lego width.

I'm starting to wonder if it might be part of some missile launching set, but if not, what kind of piece is it?

It looks like there is some sort of ribbing on the inside. Any chance you can get a better picture of that? It's likely where an official LEGO part number or at least a brand stamp might be. –  Nathan Stohlmann Feb 11 '12 at 3:22
    
@NathanStohlmann There is a LEGO brand stamp, but I think it is an older piece as it has no part number that I can see. –  RedRiderX Feb 11 '12 at 15:06

Hooray, I get to answer a question!

This is not a piece for launching missiles. It's actually part of an old steering assembly from some late 80s and 90s Technic sets.

Here's what the whole thing looks like:

Technic Rack and Pinion

And a view of the piece in question:

And an example of how it is meant to be used:

Usage example

The teeth on the outside of the piece help lock it into one of several different inclinations, so you can vary the angle at which the steering column exits the assembly.

Here is the piece on BrickLink: http://www.bricklink.com/catalogItem.asp?P=2790 (ooooo four digit part number!)

Along with the bottom assembly: http://www.bricklink.com/catalogItem.asp?P=2792

The main rack: http://www.bricklink.com/catalogItem.asp?P=2791

And the steering arms: http://www.bricklink.com/catalogItem.asp?P=4261

And that's a model answer if I ever saw one –  Joubarc Feb 11 '12 at 6:13
