Pfft does it even have a Mandolin crystal?
most likely, yes.
Keep in mind this is a 1386303: The very first model M. It predates even the industrial one by a few months.
I'm not sure if I recall how old killerbee's oldest model M was, but it's surely not that much older than this. I do note that they have different keycaps.
But guys, it's very rare and hard to find ![tongue :p](https://cdn.geekhack.org/Smileys/solosmileys/tongue.gif)
It really is. 1386303's don't show up every day like 1391401's do. Especially not in this condition.
