I thought I should take a few reference pictures to remind me how this thing goes back together. Under a layer of brown crud, I found the final two tiny grub screws fastening the bottom of the key comb to the main part. Easing the clogged comb up over the keys was slow progress, but only after making a note of which key goes through which slot. The two space bar restraints (one of them is blurred in the foreground) needed one of their screws removing so they could swing down to allow the removal of the bottom part of the comb. I also had to lever the bottom edge up to clear the key tops. The metal seems to be coppery under the black paint.
Anyone else ever had to this? If so, this would be an ideal opportunity to share the answer two questions:
- How do I remove the solidified crud? (First try will be gentle scraping - after that I'll get more abrasive)
- What do I replace it with? (I was thinking 3-4mm soft rubber strip/tube)
