HMAS Arunta II received an unusual gift when the HMAS Arunta I white ensign was presented to the ship while in Tasmania for the Royal Hobart Regatta.
The flag was held by the now deceased Cedric Pretyman, who served on Arunta I during WW2 from April 1, 1942, as a signalman.
His family presented the ensign and other memorabilia to the ship during an open day.
It was by chance the family of the WW2 veteran learned that Arunta II would be in port in Hobart, and they took a chance showing up at the security gate with items they had discovered following Mr Pretyman's death.
Granddaughter of Mr Pretyman, Kadie Pretyman, said the family wanted to donate the original ensign and photos because they were part of Arunta's history and belonged with the ship.
"My Poppy (Cedric) would be happy and proud it's back with its rightful owner," Ms Pretyman said.
Ms Pretyman said her grandfather would tell them funny anecdotes of his time in the Navy, including that he once went to a movie and on returning to the ship found it was not there. Apparently, there was an emergency and the ship had to leave suddenly.
"It was a funny story Poppy told us. Arunta I came back later into port so Poppy was able to jump on board," she said.
Ms Pretyman said her grandfather loved his time in the Navy and even aged 99 he could still remember the signals and Morse code.
Commanding Officer Arunta II Commander Jason McBain said it was a surprise when Mr Pretyman's family turned up with the memorabilia and ensign.
"They were just so keen to hand over the ensign and memorabilia to the Navy as they believe that's where this will be appreciated the most," Commander McBain said.
Ms Pretyman said her son Hudson and husband Duncan were thrilled with the experience.
"It was fantastic that Duncan and Hudson were able to be shown around the ship. Hudson had an amazing time and told all his friends," Ms Pretyman said.
"Everyone was so kind to them during the visit. Thank you for everything."
Commander McBain said they were planning to get the ensign mounted in a frame.
"To make sure it has pride of place where people can view it regularly and will be passed down from Arunta II to any future vessels that bare our name," he said.
