Bronze next of kin plaque, showing on the obverse, Britannia holding a laurel wreath, the British lion, dolphins, a spray of oak leaves and the words 'HE DIED FOR FREEDOM AND HONOUR' around the edge. Beneath the main figures, the British lion defeats the German eagle. The initials 'ECP', for the designer Edward Carter Preston appear above the lion's right forepaw. A raised rectangle above the lion's head bears the name 'SYLVESTER JAMES NIMMO'.

Born in Sydney in 1898, Sylvester James Nimmo was employed as a lithographic printer when he enlisted in the AIF on 15 August 1915, aged 16 years and seven months. After initial training he was posted as a private to D Company, 17th Battalion and assigned the duties of a stretcher bearer, possibly on account of his young age. He was also a member of the battalion's band. Nimmo left Sydney with his unit for overseas service on 12 May, aboard HMAT A32 Themistocles.
After training in Egypt until mid-August the battalion arrived on Gallipoli in time to take part on the final battle of the August Offensive, at Hill 60. Nimmo contracted dysentery in October and was evacuated to Malta, and then England for treatment, before returning to his unit in Egypt in March 1916, before it was posted to France for service on the Western Front.
He was with the battalion in all its major battles at Pozieres in 1916, Lagnicourt, Second Bullecourt and Menin Road. Nimmo was promoted to lance corporal in July 1917, and corporal in September. During the third battles of Ypres, at Passchedaele Ridge he led five parties of stretcher bearers for 36 hours carrying wounded through the German artillery barrage before he was hit by a shell on 9 October as the battalion was withdrawing from the front line. A witness saw him lying in a shell hole, wounded in both legs, with one apparently broken. Nimmo was not seen again and his body was not recovered for burial. His name is commemorated on the Menin Gate Memorial. He was awarded a posthumous Military Medal for his actions on the day of his death.

This commemorative plaque was presented to Nimmo's widowed mother, Christina Marie Nimmo, in September 1923.
