Condition: In great condition for its age, with expected signs of use and wear! The A-7 was based on the instrument that Pioneer had introduced in 1931, but equipped with a finger activated pencil that enabled the navigator to make a number of vertical marks on a piece of roughened gray paper mounted below the index knob. After each series of shots, these marks would be visually averaged, and the average time of the series determined from a stopwatch. Although the technique was relatively crude, the Army boasted that an experienced navigator using an in instrument of this sort could set his plane down at the end of a transoceanic flight within an error radius of only 15 miles, less than four minutes flying time.
