I've never seen the green and blue enter keys before, are those common on Industrial boards?
Cool keyboard though. I imagine this will go for a lot.
Coloured Model M caps are fairly rare, and to my knowledge, this is the only on with coloured enter keys. Usually it's Ctrl/Alt/Shift that gets coloured Blue/Red/Green respectively for old wordperfect overlays.
The fact that dying is easy also means that if some organization puts in a mass order with unicomp and tells them to dye some keycaps, unicomp can easily do it. It's not a collectible thing.
I have colored ones all over my board. If originally new, most of my dyed keycaps look exactly like original Unicomp ones bought new and can't really be distinguished.
I would advise everybody not to get distracted by the keycap colors. If you want the keyboard, bid on it because it's a rare Industrial that looks in very good shape.
