W&B find. How would you proceed

[yotebuster1200]

My wife and I were out checking out some antique stores and I came across this razor. They had it listed for $40.00 and I talked them down to $25.00 I have no idea of that is a good deal because this is the first vintage razor I have bought. Funny story about the razor. when I wad looking at it the lady helping me told me the barbers notch wad put into a blade when the Barber retired. She said when he retired he would take a pair of pliers and clip the notch out of the blade. It made me smile haha.

So I was wondering if anyone had any information on this razor? Age?

I was also wondering how to approach the chip in the blade. I know I will have to take the blade back to that point. This will leave me a blade thickness of about .010 in behind the edge. Should I tri to thin the blade down (while trying to preserve the blade etching) a little closer to. 005 or so? Or would you just grind it back and gone the thing up?

Thanks for the help. Any other tips or information would be appreciated.
