What do you mean by the "upper list"? "kaput"? Do the keys not work at all, or is it the shifted functions (sigma +, y**x, etc.)? (The latter would be real weird . . . ) If the keys don't work, why apply letters? (What purpose would the letters serve anyway?) I'm curious -- I'm sure you have your reasons . . .
On my 42s-in-a-17B-wrapper, I painted the keyboard with flat black enamel, then used 600 grit sandpaper to re-expose the keytops I wanted to see. I haven't seen the paint wear through yet, after years of (albeit occasional) use.
It seems to me there have been press-apply lettering kits with which one rubs the desired letter image with a hard, smooth implement, and the letter is transferred to the surface underneath. Someone will know where to look for such. Maybe office supply stores? You might try hobby shops -- I know such lettering is (or used to be) used for model airplanes, though the choice of fonts there will be limited!
