Rare variant ASTRO COMPASS MK II Sperti w Case Mk2 Vtg Antique WWII #42-20418-P

Description: Rare variant ASTRO COMPASS MK II Sperti w Case Mk2 Vtg Antique WWII #42-20418-P. What a great find in really nice used condition. I do not know much about these kind of collectibles but after doing some research on this item I believe based on the number on the unit & the tag on the box that it is possibly an earlier model than most of those being sold with the model# CONTRACT NO. W535-AC 36492. This one refers to it as an order no not contract number. It also does not have anything listed under the W.W. Boes Co. which I believe must have come after the Sperti Co. Anyway this I believe IS a RARE find & in great condition. Box is even pretty nice. Does show some wear & may have some imperfections since it is most likely form the 1930's or 1940's. One of the blocks came unglued but is NOT broken just needs to be glued back on. Here is info I have discovered thru research: Used by pilots and navigators to determine accurate true heading by the sun or stars in arctic regions. 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.The astrocompass functions by means of measured movement in three independent axes. The uppermost member contains a peep sight for stellar use and a shadow bar for use with the sun. The main platform is adjustable by reference to two integral spirit levels while mounted on the base.Additional DESCRIPTIONAt 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 surplus soon thereafter.MEASUREMENTSoverall: 15 1/2 in; 39.37 cmoverall: 10 in x 5 in x 6 in; 25.4 cm x 12.7 cm x 15.24 cm Truly a great find whether you use it or just put it on display!
