How could the key labels rub off? I thought the keys were double-shot. Or are you talking about the labels on the face of the unit, rather than the labels on the keys themselves?

Don't bother. Just buy a broken HP 67 from eBay and swap
the inards.

IF...you mean the labels on the keyboard itself (gold or blue lettering), then you should use rub on transfer lettering found in many electronic shops. Do this with the unit disassembled and all the keys removed. After it's done, mask the display and spray clear matte acrylic on the keyboard to seal the letters and prevent them from rubbing off.
IF.. on the other hand, you mean the lettering on the slant face of the keys (black color), just use enamel model paint and a very fine brush or sharpened toothpick.
And I'm sure you don't mean the lettering on the tops of the keys, as they are double injection molded. Meaning... you could sand down the top half of the key and still see the lettering.
Hope this helps,

john - i may be wrong, but wasn't it mark hoskins that made those aluminum replacement labels? if it was look for his new address on ebay in his ad/auction of hp67 card reader sticky wheel kits. if not, use the mohp search to look back a year or so for a series of posts on this subject. it was a long bunch with a lot of titles and a lot of flames by people who were worried about the resale value of their calculators against the guy who made the labels. he ended up just printing "replacement label" somewhere on them. that seemed to satisfy most of the "glass case full of hp" (i'm one of those) types and all the people who still use the old stuff (i'm one of those too).
