P1876 bayonets were initially only marked with the War Department arrow, and Enfield inspection marks. From July 1882, the date of manufacture was added to the factory stamps. The majority of the Common bayonets were manufactured by the Royal Small Arms factory Enfield.
The blade is triangular with blunt edges and was purely a stabbing weapon. The Martini Henry Pattern 1876 socket bayonet, officially named the “Bayonet Common Long” was nicknamed the 'Lunger' by the troops.
