Original U.S. WWII AAF Astro-Compass Mk. II by The W.W. Boes Co. in Original Case

Item DescriptionOriginal Item. Only One Available. At high latitudes where magnetic variation can be erratic and the angle of magnetic dip can be steep, magnetic compasses are essentially useless. This instrument, on the other hand, indicates true north when pointed at a known star. It was made for military use during World War II, and surplussed soon thereafter. It is well suited for aligning a boat's compass while away from shore-based magnetic interference. It is also useful to celestial navigators and amateur astronomers for identifying stars. It also functions as a pelorus with extremely fast operation.This is a great Astrocompass Mk. II in its original case. The data plate reads:ASTRO-COMPASS MK IICONTRACT NO. NOa(s)3438F.S.S.C.
