Pte Julius Rudolph "Ru" Jacobsohn is in the back row fifth from left.
I am wondering whether this photo shows a last militia camp prior to enlistment in August 1914, or did they report in (with friends and family) wearing their militia kit? Jacobsohn enlisted at Essendon on 17 August 1914, and his regimental number is 48. By 1914 Jacobsohn was a Lieutenant in the Victorian Rifles, but is not wearing officer's uniform in this photo. At least I don't think he is.
