M13 is the only game in town if you want Black Model M keys with lettering. I gotta stop typing on this GI Joe Mini with black keys right now and do some key coating experiments.
It's just weird how the black keys bring out the green in the Industrial Mini. This came from Brian O'Neill (rarekeyboardstore) in brand new condition with no missing rivets.

Do those black keys get shiny after a while? That's one of my pet peeves with black keys.
