W.F. Stanley & Co. Ltd. “Heath” Marine Sextant No. 77540
Certified 25 November 1977
Original Hardwood Case

An authentic professional marine sextant manufactured by W.F. Stanley & Co. Ltd. of New Eltham, London, England.

This instrument is a late-production “Heath” pattern micrometer sextant, serial number 77540, retaining its original fitted hardwood case and factory examination certificate mounted inside the lid, dated 25.11.77.

The sextant features:

• Three-circle open-frame construction

• Black wrinkle-finish frame

• Precision micrometer drum

• Original telescope

• Original optical filters/shades

• Original fitted hardwood storage case

• Original inspection/calibration certificate

Unlike modern decorative reproductions, this is a genuine navigational instrument manufactured for practical celestial navigation use during the final decades before GPS navigation became dominant in maritime operations.

Condition:
The instrument presents very well with strong original finish, clean optics, and an attractive untouched patina consistent with professional maritime equipment of the period. The hardwood case remains structurally sound and displays beautifully.

This sextant would be appropriate for:

• Maritime collectors

• Nautical museums

• Scientific instrument collectors

• Blue-water sailing enthusiasts

• High-end nautical interior display

• Celestial navigation practitioners

A rare surviving example of late 20th-century British precision navigational craftsmanship.
