Need a critique of a K Date

[Thor]

I doubt the stamps have been changed, just deepened to be more clear, a lot of time someone has attempted a bluing that ruined the stamps so they are brought back to look right, the K date I restored that was delivered today had to have the barrel reinstalled as it was really messed up and
and out of spec for chamber guage, Hugh fixed the barrel and I fixed the finish and now the owner is totally stoked about his gun.
