There is indeed a slight frown. Honing with something around 240 grit for a few laps may take care of that. Go carefully and stop as soon as it all evens out.

As far as cosmetics, I wouldn't worry about that right now. Get it cleaned up a bit and sharpened and if it shaves well then use it. After a while go for a pro restoration if you want.

I agree you'll lose what's etched on the blade if you get too rough with the cleaning - just use a polish and rub carefully and lightly if you have to buff it up. A Barbisol soak may be the safest thing to get it sanitary again. Also agree that if the scales close, don't mess with them at this point. Clean it, hone out the frown, sharpen it, and use it. Nice blade and should shave well.

Nice find!
