5923494 Indian Army Officer?s sword belonging to Lieutenant Malcolm Scrimshaw Green, Sind Irregular Horse, 1845 circa (metal) by British School, (19th century); National Army Museum, London; (add.info.: Indian Army Officer?s sword belonging to Lieutenant Malcolm Scrimshaw Green, Sind Irregular Horse, 1845 circa. The standard blade for the Pattern 1821 Officers Undress Sword was pipe backed, or round backed, and double edged for the last 22.5 cm of the blade. Some officers, particularly those serving in India, preferred swords with a large latch back or kilji balde which gave a pronounced double edge that was wider than the rest of the blade, and a point which it was thought could penetrate chain mail armour more effectively. This type of blade is associated with the sword cutler John Prosser who claimed it as his invention in 1817. By about 1850, when he made this sword for Green, with its non-standard hilt and blade inscribed with his name and arms and the title \'Scinde Horse\', this type of blade was obsolescent. Lieutenant Green (1824-1906) was the third son of Rear Admiral Andrew Pellat Green.); by National Army Museum .
