No one will trade you, this is exactly the reason why the XT keyboard is relatively cheap and the AT one expensive. ;)

I totally understand that no one would trade me. I should have made that more obviously a joke. :)
You could build yourself a XT-to-USB adapter. Buy a Teensy 2.0 USB ...

UV will degrade plastics. He should have covered it in peroxide and oxi clean before blasting it with UV. Then it would be clean and would reverse any yellowing.

I have had an old IBM PC-XT keyboard for some time. It's the original XT style keyboard, sometimes known as a Model F, though I guess that really just refers to the capacitive sensing switch that's used.
