Authentic WWII-era Swivodex inkwell issued by the U. Navy, manufactured by Zephyr American Corp. Marked PROPERTY OF U. The base is made of black glass with a rotating marbled Bakelite collar, designed to prevent ink spills in rough seas. A vintage dip pen is included. While it appears era-appropriate, it is not original to the base and has a broken nib tip – still makes a great display companion. Great condition overall with only light age wear (please see all pictures). A great addition for any militaria, U. Navy, or vintage pen collector.
