I'm showing today a silver figural seal (animal), mechanical pencil. The pencil is marked MacMichael, (a known London jeweler, silversmith). The writing tip is simultaneously deployed from the mouth of the animal when pulling the rear section away from the body. People in the hobby refer to this deployment type as 'magic pencil'. It's actually just fancy internal gearing. Circa 1880'ish. The piece is 1 7/8 inches closed and 2 3/4 inches extended.
