B66-479 POCKET COMPASS WITH TELESCOPIC SIGHT. W. & L.E. Gurley No. 312. Gurley's line of "pocket" compasses were designed for greater portability than full size compasses, and were offered in plain, railroad and vernier models. The folding vanes could be used in the traditional manner, but Gurley also offered a version in which the vanes were offset from center, and could be folded together to support a sighting telescope. This is the vernier model with the scope, and also included Gurley's optional four screw leveling adapter - clearly a deluxe model. 4-1/2" needle with silvered dial, in original mahogany box with the scope, original plumb bob, leveling adapter, screwdriver and wrench; good label in the lid. The case is missing its leather straps, but otherwise in absolutely immaculate condition. From the collection of Chuck Morgan. Fine 400-800
