The Randomness of Unicomp Keys

I was looking closely at my Unicomp keyboard, trying to figure out which keys are 2-piece and which are 1-piece.  Based on the keyboards I have (1 1994 Model M and 2 Unicomps), the pattern that emerges is:

• Normal keys and 1.5 unit keys (Ctrl/Alt, Tab, and backslash) are 2-piece.
• Larger keys on the Model M (ones with the guide pin, space bar, etc) are 1-piece.
• The 1.25 unit modifiers on the Unicomp keyboards are 1-piece.
• The "notched" G/H/B keys on the Endura Pro are also 1-piece.

The bottom part of the keys are a grab-bag of colors:
