Unitek K-151L. This is my first foray into linear switches, Cherry MX Blacks to be specific, and they are wonderful.
I'll get pictures tomorrow in the daylight, as despite having all the lights in the cab on, my lousy camera-phone can't take a decent pic in this low of light. See, I have one of those old-fangled 'dumbphones' at the moment. Yeah.
The entire bottom of the thing is metal. And it has an AT-XT switch. Damn, that sounds like something out of Star Wars.
