You are bidding on an EXTREMELY RARE and BOXED example of a Japanese Navy Surveying Protractor / Navigation Computer!  This was captured by a US veteran at the end of the war and is 100% complete! 


Navy personnel used this device to accurately plot the ships direction and location.  The 3-arm protractor was used by many nations of the nations in marine surveying.  The ship’s position can be quickly located on a chart, when the angles between the fixed points are known.


Made of brass, wood, and steel, and dated August 1941, this navigational computer is in AMAZING condition!  It is 100% complete, along with 3 additional arms that can be added to extend the protractor legs (for larger maps), as well as the original loop.  No breaks, damage or wear!  It comes complete in the original wood box, that features Kanji writing on the top, as well as the Tokyo Navy Base stamps on the inside of the lid.  Also retains the original data plate.  Like most Japanese items is an EXTREMELY rare item, perfect for any collection or display

——————- TERMS OF SALE —————–

Most of my items are vintage, and as such are AS-IS, so you must therefore expect a degree of wear due to age and/or usage. I will describe each auction to the best of my knowledge and take as many photos necessary to ensure you are pleased upon receiving your item. All sales are final, so please make sure your questions are answered to your satisfaction before you purchase.


——————- ABOUT ME —————–

Although my passion is the Me109, I do offer many other German Aircraft (Fw190, Me262, etc.), as well as USAF and Japanese items. Occasionally I do offer many non-vintage items such as prints and art relating to the time period. As a private collector myself, I am constantly on the lookout for historical memorabilia, authentic photographs, artwork or anything unique relating to military aircraft.
