So I have been customizing my Unicomp Classic Model M for the past few months with different colored keycaps and whatnot and recently noticed that I have so far received about 3 different styles of keycaps. So far they all look about the same from the front but the underside will be different.
Look at these photos, you'll notice that one of them is the old school 2 layer keycaps that my old Model M had while the other 2 are just 1 part. Also notice that the newest one (in the middle) has a different shape of clips for attaching to the barrel.
