This lot features an authentic, early 20th-century automotive artifact pairing consisting of an original Ford Motor Company threaded octagonal grease hub cap and a companion aluminum inner wheel hub dust seal plug.

The threaded cap is stamped with the classic vintage "Ford" cursive script and a "Made in U.S.A." geographic manufacturing mark on its exterior top face, mirrored cleanly by an inverted counterpart pressing on its internal surface.

The separate press-fit inner cup element includes structural alignment steps along its base wall and carries an internal product designation code reading 0055-2 alongside three-letter identification stamps.

Both items preserve a rich mechanical patina highlighting surface oxidation, historical tool-contact wear, and residual assembly coloration consistent with 1910s to 1920s vehicle application.
