Included in this lot is "The Bullet's Flight The Ballistics of Small Arms, The Internal and External Ballistics of Small Arms; A Study of Rifle Shooting with the Personal Element Excluded, Disclosing the Cause of the Error at Target", by Franklin Mann, illustrated with 188 Plates showing the results of over 300 Rifle Experiments performed and chronologically arranged. Franklin Weston Mann (1856–1916) was an American physician and inventor and author of this pioneering ballistics text. 1894 he was conducting experiments with the aid of precision crafted guns and ammunition on specially designed equipment to minimize and measure sources of error. Results of his investigations published in 1909 are commonly known as The Bullet's Flight. The precision-machined vee-shaped cast-iron steadying cradle he invented for his investigations was adopted in 1920 by the National Institute of Standards and Technology and Aberdeen Proving Ground, and has been widely replicated for ballistics investigation as a "Mann Rest". His 1909 publication had secretly been studied by European combatants building long-range artillery of World War I.
