I have what may be? the last sextant used on the America. She was hauled out in 1902 to be laid up in Annapolis; the sextant I have is in a mahogany case with a german silver plate on the front, engraved with a line drawing of the vessel, and “America, James Waters, Master, 1902”. My Dad was a sea scout leader just before WWII and was looking for a sextant to teach his scouts elements of celestial navigation. Someone sold him this sextant for $10.00. Pretty cool artifact!
