Sterling Silver WW II Nepal Contingent British Forces Commemorative Plaque

Description

One-of-a Kind!
Sterling Silver Plaque that is engraved as follows:
PRESENTED BY His Honour Colonel Kiran Shum Shere Jung Bahadur Rana of Nepal Who with his Officers and Men of The Mahindra Dal Regiment Donated Blood at this institution During September 1942
The Mahindra Dal Regiment was the Nepalese Contingent under the command of the British Forces
HISTORICAL - search for "Kiran Shumsher Rana" on Google or Wikipedia to learn more about who this "Colonel" was and who he became afterward.
Weighs 56.5 grams
Slightly curved (that's why I had to weigh it upside down).
See "Sterl. Silver" Mark on back
No information on which "this Institution" it is referring to but I'm sure a history buff can ascertain where he and his men were located During September 1942
