Thornhill of England produced this silver mechanical pencil fashioned as a mythical dolphin or maybe just a plain ol' fearsome sea creature. The material is silver. The writing section is deployed by pulling the whiskers away from the head of the beast. It was produced during the 1880 - 1895 period. Without the ring assembly, the pencil is 1 1/2 inches in length closed, and 2 3/4 inches ready to write.
