Compass, Aircraft, Direct-Reading Magnetic, Type 51 w/Fishbowl Lens
Here is a vintage Aircraft Compass, Magnetic, which we believe is a Type 51 made by Aeromarine based upon a similar model viewed online. We believe it to be a pre-WWII model for civil aircraft, but interested parties are invited to do their own research.
This compass is in exceptional condition given its age. The fluid is intact and clear. The teardrop-shape case is unblemished. There are adjustment knobs at the bottom one for gross adjustment and the other fine. Face measures 3.25 inches across and ~5 inches long.
