Sexton GPO (Gun Position Officer) “DARLING” of D Troop, 36th Battery, Canadian 23rd Field Regiment on parade in the Netherlands at the end of the war in 1945. It looks like this GPO was converted from a Sexton Mk.I (note the 3-piece final drive asssembly and M4 bogie and regular VVSS track).
Archive caption: "Sexton self-propelled howitzers passing in front of a reviewing stand at a parade. Date: 1945. This shows a parade (likely a VE-day parade in Holland) where a battery of Sexton self-propelled howitzers are being reviewed. The vehicles are from the 23rd Field Regiment, Royal Canadian Artillery, 4th Canadian Armoured Division. The vehicle closest to the stand is a Gun Position Officer variant of the Sexton."
