You are bidding on a SUPERB example of a 100% original WW2 USAAF / US Navy Aircraft Load Adjuster/Slide Rule Calculator!  Though this type was used on many various aircraft types, this one is specific to the B-24 Liberator, and PB4Y-2 Privateer!


Made of wood and plastic this is of late-war production and is in AMAZING unused condition!  Specific to the B-24 and PB4Y-2 Aircraft, it is 100% FUNCTIONAL!  This item allowed the crew to calculate the most optimal bomb, fuel and ammunition load for a given mission, balanced against the weight of other equipment, including turrets, bunks, cameras, and the crew themselves. The reverse of the instrument also shows a simplified diagram of the fuselage layout of the bomber.  Comes complete in the leather original case, that is marked “US Government Property”, along with the original instructions; 3 blank tags; the original mounting clamp for inside the aircraft; and the original box!  Approx. 12″ in length, this is the most complete example I have seen!  Would be a PERFECT addition to any collection, restoration project or simply for display!


Please email me if you need additional photos or information.

——————- 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.
