An awesome 6″ White I‑navigation rule, a compact and beautifully made little instrument carrying multiple navigation scales on both sides. The white material is clean and evenly toned, the graduations are sharp. These small navigation rules pack an impressive amount of function into a pocket‑sized form, and this one has that crisp, well‑preserved look that makes them so appealing to collectors of early mathematical and nautical instruments.
