The Pioneer 1829-2-A Magnetic Compass was used in various US military vehicles and naval craft during WWII.  It has a screw-type heeling compensator, a removable drawer-type compensator, a screw-type horizontal compensator, and a spider-type compensator, all for the elimination of errors caused by magnetism. Has a constant deviation corrector and a course setter. With a rotatable dial engraved with the compass card graduations. The compass mounted anywhere and rotates within the the framework of the body to give another thirty degrees of adjustment. Also, has a rotating disk with Pioneer and numbers on it for us as a course reminder. Measures approximately 8.5 inches tall by ~5 inches wide.

This example is new old stock in its original carton. The fluid is intact. The luminous scale on the compass card has faded with age but is clearly legible. The rubber vibration mounts are intact. The brass adjustment tool is in-place. It is in exceptional condition given its age.
