WW1 47th Sikhs, British Indian Army button.

19mm brass button for the 47th Sikhs, British Indian Army.
The 47th (Sikh) Bengal Infantry was raised in 1901 in Sialkot, in the north-east of Punjab (now in modern-day Pakistan), and was renamed the 47th Sikh Infantry in the same year.
During World War One the regiment served on the Western Front and in the Middle East, as part of the 8th Indian Infantry Brigade, fighting at the Battle of Megiddo in September 1918.
In 1922 the 47th Sikhs became the 5th Battalion, 11th Sikh Regiment , which means this button dates to between 1901 and 1922 — the regiment’s entire existence as the 47th Sikhs.
