Gurley Surveyor's Compass

Gurley Surveyor's Compass

<< >>
Usage conditions apply
This compass was made between 1853 and 1859. The "Jas. W. Queen, Philada. Warranted" signature indicates that James W. Queen sold the compass and guaranteed its quality. The style, however, indicates that it was made by W. & L. E. Gurley, the Troy, N. Y., firm that was rapidly becoming the largest producer of complex mathematical instruments in the United States. The Queen Catalogue of 1859 offered several compasses, levels, and transits, with illustrations and descriptions copied from the Gurley Manual of 1855. A compass of this sort, with 6-inch needle, two straight levels, outkeeper, and mounting for use on a Jacob staff, cost $30. A paper label inside the box reads “James W. Queen 264 Chestnut St., near 10th, Philadelphia.”
