Today I'd like to show a Sampson Mordan Muscovy duck head, figural mechanical pencil. To operate, pull the ring end away from the body and watch the lead nozzle simultaneously extend out the other side. The mechanism is referred to as a 'magic pencil' Circa 1880 - 1890. The duck is 2 1/8 inches long compressed and 3 7/8 inches in the writing position.
