Vicks,
The 11th Gorkha Rifles were a new regiment of 3,398 men and officers from the 7th and 10th Gurkha Rifles who opted for service in India after independence.
They were designated that in February of 1948 and their last posting that I know of was in Lucknow in 1983.
India has kept 4 or 5 Gurkha Regiments and many are mixed with other Indian Regiments and battalions.
In July of 1994 the 2nd, 6th, 7th and 10th were amalgamated into one Regiment designated the Royal Gurkha Rifles in England.
The Gurkha Reserve Unit formed in 1981 still continues to serve in Brunei and there still is The Gurkha Contingent of the Singapore Police.
