This is a solid brass reproduction of a large antique pocket compass. The antique patina compass looks just like a 100 year old antique. The antique finish requires no maintenance and can be handled without fingerprints discoloring the brass. There is a small lever on the side of the compass that operates a needle lift mechanism to protect the compass bearing while in transit. The compass rose is graduated in degrees and has a standard surveyor’s 0 to 90 degree scale from North and South. The compass is 3 inches (7.6 cm) in diameter, 11/16 inch (1.75 cm) thick, and weighs 8.4 ounces (238 grams).
