A flare gun lost after it raised the alarm during Scotland's worst peacetime maritime disaster has been found on the seabed.
More than 200 men died when the troop ship Iolaire sank at the entrance to Stornoway harbour in 1919.
Returning home in the early hours of New Year's Day, after surviving the battlefields of the Great War, the admiral yacht struck rocks just yards from safe haven.
Nearly 80 men made it back to shore, but almost every community in Lewis and Harris lost somebody in the tragedy which claimed 205 lives.
While diving on the wreck site 93 years after it sank, coastguard helicopter worker Chris Murray found a small rusted pistol buried in the sand.
The gun was used to shoot brightly-coloured distress flares into the air by first officer lieutenant Edward Cotter.
Tragically the signals were mistaken for fireworks, celebrating the homecoming and the New Year.
Mr Murray hopes that the newly-discovered flare gun will now take pride of place at the Stornoway Museum, preserved for future generations to remember the darkest night in the island's maritime history.
