Ok, now I have to admidt my mind is completely blown. I removed the trigger group to oil it completely and this is what I found.
Virtually no wear anyplace that usually does wear in these areas. To the best of my knowledge refinishing of these areas is not part of the refurb process but I could be wrong. The underside of the receiver, the top of the trigger and sear, the the cocking piece contact area of the sear and the same contact area of the cocking piece. Even the sear pin shows no loss of finish on it anywhere.
Anyone who knows more than me about this which is practically everyone please chime in if I'm wrong.
