British BL 7.2 inch Howitzer on an US Long Tom gun carriage in the Land War Exhibit at the Imperial War Museum Duxford.
The BL 7.2-inch howitzer was a heavy artillery piece used by the British Army throughout the Second World War.
The usual gun tractor for the 7.2-inch howitzer in the early war years was the Scammell Pioneer, although this was never available in sufficient numbers and from late 1943 the Pioneer was supplemented by the Albion CX22S.
