I think the Leave book has the initials wrong. There was probably only 1 Toone in ADRIC and that was WT Toone
John Wilfred Toone was born in February 1897, the son of a veterinary surgeon, and was educated at Rossall School before being gazetted to the Royal Irish Rifles as a 2nd Lieutenant in August 1915. Transferring to the Royal Flying Corps shortly thereafter, he qualified as a pilot on Maurice Farmans at Farnborough in early September (Certificate No. 1692) and was posted to No. 11 Squadron out in France early in 1916 after gaining further experience in No. 10 (Reserve) Squadron at Joyce Green.
Having fought at least one combat on 31 March 1916, over Souchez against an Aviatik tractor-biplane with rings painted on its sides to simulate cockades, Toone and his Observer, 2nd Lieutenant E. B. Harvey, late of the Artists’ Rifles, were downed in their F.B. 5 in a combat with three enemy aircraft over Vaulx on 2 July - he and Harvey were taken P.O.W.
Repatriated in December 1918, Toone returned to regimental employ in the Royal Irish Rifles in early 1920, after an appointment in the Air Ministry.
