The Pattern 1853 Enfield Rifle Musket embodies a number of revolutionary milestones for Britain; it, and the carbines and short rifles derived from it, were the first rifled firearms to be issued universally to all troops; its design owed more to the French 1777 musket than to its English forbears; it was the first firearm to be produced en masse extensively by machinery; in 1857 it became the first firearm in Britain to be made fully interchangeable.

The nature of this new rifle presented a number of challenges for the private contractors who traditionally had supplied military firearms and some unique contract documents specifying standards are shown. Their failure to meet contractual obligations led to the formation of the Select Committee on Small Arms in 1854 to examine its manufacture and procurement. However, its outcome was pre-empted - in that same year the Committee on the Machinery of the United States, was sent to America to examine the machinery used in gun manufacture and given authority to purchase appropriate machines for use at Enfield.

Aspects of its manufacture at Enfield are covered in a small number of contemporary accounts. These vary in the detail provided and contain errors which have been noted and corrected.

Access to a wealth of specimens, drawings and documents not previously studied or published, has allowed the manufacture of this iconic rifle using these new technologies to be presented in unprecedented detail.
