they probably just forgot to laser it..
I thought they were Dyesubbed PBT?
I don't think you guys know how these are made.
What's up with your wikis?
IBM Pad Printed Model M key on left, Dell AT101W key on right - notice the lasered lettering is somewhat faint and burnt looking
The Model M doesn't look pad printed to me in that picture. I suppose it could be lasered, but at the top it says
Laser engraving became popular in the mid-1990s
So did they start out as dyesub, then change to pad print or laser? I'm not talking about those black IBM sets either.
Anyway, I still suspect most model M keys are Dyesubb'd PBT, and I'll wait for Mr. #1 to make up his mind and update the wiki.
