Description:

Substantial hooded marine binnacle on a wood pedestal, housing a liquid compass with degree ring, side-mounted oil lamp, and two adjustable soft‑iron ‘Kelvin’ corrector balls (red/green). A cylindrical Flinders tube is mounted to one side. The compass card shows Scandinavian abbreviations (N, O, S, V), and the assembly is gimballed within a heavy brass bowl under a thick glass window.

Curator Questions

Curated by Jade

Assessment:

A complete and impressive early 20th‑century ship’s binnacle with its correction system intact (Kelvin balls and Flinders tube) and an original-style oil lamp. The Scandinavian card (O for east/Ost, V for west/Vest; NO, SO, NV, SV) points to Swedish or Norwegian use. Brass shows even patination and verdigris consistent with marine service; painted spheres likely repainted later. Glass appears original; function untested. A word about fakes.. decorative ‘nautical’ binnacles are widely reproduced, often lightweight with thin brass and non-functional parts. Here the heavy construction, gimballed movement, calibrated degree ring, and proper correction apparatus support a period, working instrument.

Condition:

Very good (honest marine patina and verdigris on brass, glass intact, repaint on spheres, lamp present; operation untested)

Identification Score: 93%

Form and components clearly indicate a Kelvin‑type ship’s binnacle: hooded brass housing, gimballed compass with degree ring, side oil lamp, Flinders tube, and paired quadrantal spheres. Scandinavian lettering on the card suggests Swedish/Norwegian service.

Authenticity Score: 80%

Consistent age patina, correct construction details, and presence of lamp and correctors argue for an authentic early 20th‑century binnacle. Minor later paint on the spheres and possible later maintenance to the card or fittings cannot be ruled out; maker’s plaque not readable, hence not higher than 80%.
