condition Keyboard pre-selected as good candidate and passed initial testing to confirm mechanical condition. Upper keyboard case disassembled and individual 101 keys have been removed and fully cleaned by hand. Inspection of interior plate. All 56 plastic rivets drilled out and replaced with M2 precision screws to restore internal integrity.  Interior plate vacuumed to remove foreign debris. Keyboard re-assembled and re-tested post-cleaning. Individual photography of rear label. Photo gallery of typical restoration workflow.
Not sure about the prior history of this particular unit, possibility #1) Lexmark factory worker was having a bad day and did not monitor dye-sublimation equipment when manufacturing keys and this is why keys appear lighter than normal or possibility #2) keyboard was built normally, but end user left the keyboard on desk in front of sunny window for years and UV radiation bleached and faded some of the keys on the keyboard.

Attached keyboard cable shows some wear.  Repaired with gray electrical tape.

A good, but not a great example of a vintage mode M keyboard.  Discounted pricing reflects these issues as noted above.  Good value for someone looking for an entry-level price or looking for a backup model M keyboard.
