Kings Norton Ammunition Collection – KN Headstamp, Birmingham, UK

This collection features ammunition produced by KN – Kings Norton Metal Co., based in Birmingham, UK, a notable manufacturer of small-arms cartridges during the 20th century. KN supplied a variety of calibres, including .303 British and other service rounds, for military and civilian use. Cartridges bearing the KN headstamp reflect the company’s manufacturing quality and consistent production standards, characteristic of British ordnance from private industry during both world wars and the post-war era. The collection highlights variations in dates, load types, and case materials, offering collectors and historians valuable insight into industrial ammunition production outside the main Royal Ordnance factories. Ideal for display, study, or reference, KN-marked rounds illustrate the contribution of private British manufacturers to the nation’s arms supply and form a historically significant component of any serious ammunition or militaria collection.
