"I was able to find out about a man who went to Australia to join the Australian Imperial Force, who then came back and fought in the trenches, was injured, lived not very far from here in Woolwich.
"All that from one little piece of metal, and it really brought that person back to life again.
"I was also then eventually able to trace where he was buried in Greenwich.
"So that one little piece of metal opened up a huge story."
Through online archives, Frederick Jury’s story began to unravel.
Ms White found he was born in 1873 and died in 1932, that he was a gas stoker in London before he enlisted with the Australian Imperial Forces, which she thinks is because of his age; at 42-years-old he may have been too old to join up in Britain but in Australia the upper age limit was higher.
Ms White then found he left Australia to fight on the Western Front having travelled from Britain to France on the SS Arundel in December 1916.
Fred fought with the Australian Imperial Forces 3rd infantry battalion, 19th reinforcement for two-and-a-half years in the trenches in Belgium and France.
It was in Meteren, France that he was severely injured.
Nicola traced his story back to find he spent time in two military hospitals The Harefield Hospital, London and the Shorncliffe, Kent.
Eventually, Fred was discharged from the Australian Imperial Expeditionary Force in London on the 23rd April 1919.
Among Ms White' other finds are several tags belonging to First and Second World soldiers and the metal bottom of a kit bag from a Great War soldier.
She thinks she finds so many military artefacts because the location is so close to where Woolwich Arsenal was located.
"I’ve found a fair few items that have people’s names on and that’s my favourite kind of find because then you can go onto ancestry or one of those sites and uncover the past and bring those people alive again for a little while," Ms White said.
