Large guns produced included the Royal Ordnance L7 105 mm tank ordnance, which was for a long time one of the most important products, and the 165 mm demolition gun that fired a very large HESH projectile and was fitted to the FV4003 Centurion Mk 5 AVRE (Armoured Vehicle Royal Engineers). Other guns included the 76 mm L5 and 76 mm L23 for armoured cars, the 105 mm L13 for the Abbot SP artillery, the L16 81mm Mortar for the Infantry, and to provide an even more tangible link with the present, the 105 mm L119 and L118 Light Gun for the Artillery.
