Thread: Sheffield Razor, Need Help Identifying and Cleaning

I have an old family razor I found in my grandparents property. I'm thinking late 1800's early 1900's. The only writing on the box that I can read is: "Geo" which I'm assuming is George, and is on the upper left side of the box part containing the insect damage; on the right side is: "1*XL" and "Sheffield, Eng." Closed the razor measures 15.5 cm. The blade itself measures approximately 13.8 cm. On the handle there is engraved "47 Live Oak". There is a Live Oak, Florida, which is very near where these relatives lived, but I don't know if the engraving is after the town name.
I cannot make out any writing on the blade itself. My Grandfather was born in 1895 and his father during the Civil War if that helps any.

Could the handle be very thin ivory, or would it most likely be plastic? What is the best way to clean this blade, removing the rust and polishing? What would be a good guess as to when this was made?
