I understand that the Ordnance 3 Inch ML Mortar of WW2 was adapted in 1944 so that it could then fire captured Italian 81mm mortar bombs. The internal diameter of the barrel was already the same (or near enough) to allow the bombs to fall down onto the firing pin but the arrangement of the firing pin in the British tube did not suit the percussion cap in the primary charge of the Brandt' type 81mm bomb. Does anyone have any further information as to why the Brandt' type bomb would not fire on contact with the original firing pin of the 3 Inch mortar?
