Lord & Harvey "Patriotic Razor"

[Joanne]

I recently purchased a Lord & Harvey razor that has a horn handle. The handle is carved and has George Washington, 13 stars, "E Pluribus Unum & Independence" in an oval, a Federal Eagle, under which seems to be a name...Witon? Wilson? a cornucopia with the word Washington below it, and what looks like a Liberty Cap. The blade has rust. It is marked Lord & Harvey on one side. I have three questions and hope you can advise me...How do you clean the horn & blade without harming either, can you estimate a date, and if it is a name under the cornucopia, is there information on the people who carved these handles for L & H. Any information would be greatly appreciated.
It was hard to photograph the handle...hopefully the images uploaded correctly. Joanne
