In 1986, divers salvaged this glass treasure, along with other historic items, from the wreck of the British troopship, HMS2 Birkenhead. Around 2:00 am on the dark morning of 23rd February 1852, her metal hull ripped open on a treacherous rock pinnacle some 150 km (100 miles) south-east of Cape Town.
