I'm pretty sure I have what you're looking for (P/N Ducky KB 1008-N ?). Green XM Alps.
If so, I would be happy to sell it to you. I bought it used, so I can't speak for the history before I owned it, but since I bought it it saw daily use by my roommate. I can provide some detailed pictures of the wear and dirt. I'd probably just like to get what I put in back out of it, so I'd ask $40 shipped CONUS. Let me know!
