My recommendation is to take a pencil and really go over the corroded bit. That'll take off the worst of the oxidation, then use some 2000 grit sandpaper, preferably wrapped around a wooden dowel or something equally firm, and just lightly sand the surface to make the etch a bit clearer.
As for age, it's definitely from near the beginning of their run.
Imho, 1820-1825.
Here are two more examples with a similar blade pattern and stamps.
As for the S on Butcher, it's almost certain possessive. As in "Wade & Butcher's"
There may have been another stamp or a blade-face etch of something like "universally approved razor".
