Were the Legendary Thinkpad Keyboards Made by Keytronic?

I just saw this that looks like the Thinkpad keyboard that we all love, and it happens to be sold separately so you can see the IBM part number and label, which also states "Manufactured for IBM by Key Tronic":

So were the Thinkpad keyboards made by Keytronic?

Yes. There have been many manufacturers of ThinkPad keyboards, including also Alps and NMB.
Keyboards from different manufacturers have had tiny differences in the details such as different colours on the Alt keys.
Not all have been scissor switches: older keyboards have had rubber rings with a centre post that touches the membrane when the keys bottoms out. I think the Key Tronic-made keyboards are like that.

There have also been several manufacturers of the trackpoint.

Thank you so much!  I actually have two older laptops that have the IBM Thinkpad keyboards, and each one has a slightly different feel--now I know why.
