Brass Marking Disk for SMLE #1 Mk III

[RobD]

The Indian Army fought with distinction in the Great War, and the 119th Regt was a good example of this: from Wikipedia I learn that:
The 119th Infantry (The Mooltan Regiment) were an infantry regiment of the British Indian Army. The regiment traces their origins to 1817, when they were raised as the 1st Battalion, 10th Regiment of Bombay Native Infantry.
The regiments first action was in the Battle of Ghazni during the First Afghan War. After Afghanistan they were involved in the Siege of Multan in the Second Anglo-Sikh War. They then returned to Afghanistan again and took part in the Siege of Multan, in the Second Afghan War. During World War I they were attached to the 6th (Poona) Division and served in the Mesopotamian campaign. They fought in the Battle of Basra, the Battle of Qurna, the Battle of Es Sinn before being delivered a setback at the Battle of Ctesiphon. Following this engagement, they withdrew to Kut. Trapped in the city during the Siege of Kut they were forced to surrender after 147 days.[1] A second battalion was raised from men on leave and reinforcements and sent to Mesopotamia.[2]
After World War I the Indian government reformed the army moving from single battalion regiments to multi battalion regiments.[3] In 1922, the 119th became the 2nd (Mooltan Battalion), 9th Jat Regiment.[4] After independence they were one of the regiments allocated to the Indian Army.

The disc is thus from rifle number 416 of the 1st battalion of the 119th regt. That rifle was brought into service in Feb 1914. It would be perfect for an early-dated SMLE.
