The first looks to me like staining or oxidization or something of that nature. I have not seen a blade like that goldwashed, and it wouldn't make sense to me for it to be on the tang and that area of the blade.

The second is a much older stamp that W&B used. The WR is for King William, though I don't remember which one off the top of my head. Given the stamp, the tail, and the look of the shoulder, I would say with near certainty that the blade was reground.
