Hadley Octant

John Hadley’s octant of 1731 is the instrument the modern sextant was built on. We draw it laid flat, arc up, with the mirror frames and index arm picked out. Edition of 50, hand-numbered.

Every design is drawn from observation — chart, harbour, or headland reference — not from stock clipart. Made to order in Cornwall. Hand-numbered when it's a limited run.
