Correct me if I am wrong here, but the op specifically mentioned the possibility of rebluing in their post. Cold blue is not reblue.
FWIW, if they were my fathers firearms handed down to me, I would have done just that - hence the Evaporust suggestion.
I'm glad the OP made his choices and is happy with the result.

Yes I did ask about re-blue, but it was more a question since I did not know what to do. Right now I want to use them so I felt this was the best option, and it looks great, can always re-blue in the future if I feel so inclined.
