Any Victorian gentlemen or lady would have treasured a unique piece of jewelry. It was fashioned from a boar's tusk and it has a silver cap and C-clasp.
The cap is removable and likely used for holding snuff. It is incised with the following: a partial name WILH, then a J or I or L; this is followed by a very tiny oval with an unidentifiable mark inside (too worn to see or photograph clearly); next to that is a letter and number, C 7.
The style of lettering is early 19th century but I was not able to identify the maker or where the piece was made. The pin is approximately 3 inches long and around 7/8 inches wide.
Silver is tarnished. Tip has a small flake off of it and the narrow portion of the tusk on one side has flaked. There's a tight line on the outer curve, running between the silver mount and cap.
