Davenport Surveyor's Compass

Description
This is a wooden compass with a paper card that is marked "ANTHONY DAVENPORT, PORTLAND." Davenport ran a mathematical instrument shop, At the Sign of the Quadrant and Compass, in Portland, Me., during the period 1823-1838. Most of his wares were for nautical use, but according to an undated trade card now in the Mystic Seaport Museum, he also sold "Brass and Wood Surveyors' COMPASSES." The Davenport signature on this example appears on a small circle of paper that has been pasted over the name of the man for whom the compass card was originally made. The words "Callender scp." on the card refer to Joseph Callendar (1751-1821), an engraver who produced the plates for the compasses and trade cards used by several New England instrument makers and dealers.
