For today’s researcher into Enfield ammunition, the definitive reference is “Rifle Ammunition. Being Notes on the Manufactures connected therewith as conducted in The Royal Arsenal, Woolwich” by Arthur B. Hawes, Captain (r.h.p.), Bengal Army and published in London, 1859. Hawes writes in his introduction: “These notes, intended at first only for myself, were, I am happy so say, useful to others; and from that reason more than any other, I am induced now to offer them, imperfect as they are, for the perusal of all who feel interested in the preparation of ammunition of different descriptions, with the exterior of which all soldiers are so familiar.”
