One high-grade late 1960's vintage Japanese metal sextant, Simek Mk III, in excellent condition (never dropped, in alignment), with locking wooden case, documents, $500.
Also have one Davis Mark 25 plastic student sextant, very good condition, with plastic case and instuction booklet, $100.
Terms: Can't accept trades. Buyer pays shipping. Strongly prefer pickup for the metal sextant, as professional-quality sextants are delicate precision instruments. I live north of Boston, MA and will drive reasonable distance.
