No kidding, that's why I asked what it was. If I had to guess, it seems like the stuff on the alpha block was acquired through luck.
This is what my AT101 looks like. I couldn't stand the shiny keys on it, so I removed them. At least, those that I could. The spacebar I painted to get rid of the shine, and I intend to repaint it with a textured rustoleum on top so that it'd be better.
The obviously nonstandard keys are from some dome board that was trashed, and I bought the keys from the person who did it and he was in malaysia IIRC. (could look it up) So they were definitely gotten by luck. I had no idea when, or even if, I was going to use them when I bought them. They are ABS doubleshot fairly thin, and with lots of texture left on the keys.
