Antique Estate Horse Hoof WALKER Snuff Box or Similar Needs TLC Black Americana

Description

Here I have a 19th Century Horse Hoof Snuff Box.
The hinged lid stamped to the underside with W. WALKER.
This old horse hoof lidded box has suffered from bad storage.  Needs TLC.  The horseshoe itself has oxidation.  The hoof is deteriorating.
This is an estate find out of Kentucky.  I'm thinking maybe a presentation to William Walker at one time.
From Research:
Walker rode in the very first Kentucky Derby, held in 1875. Walker took fourth place aboard the horse Bob Wooley. The next year, Walker rode the horse Bombay and again took fourth place.
Walker won the 1877 Kentucky Derby aboard Baden-Baden by a two-length victory. Edward Dudley Brown, another successful African American in the Thoroughbred racing industry, trained Baden-Baden.

Walker rode for the fourth and final time in the 1896 Kentucky Derby, and placed seventh on the horse The Winner.
