File 47-S/43 Proposed award of an C.B.I. to Subedar Major Sarwan Singh of the 4th Gwalior Infantry. This is a file at the National Archives. Does anyone know what a C.B.I. award is?
I suspect it is a typo and should read O.B.I. – Order of British India. N.B. The file is actually held by the British Library: Asian and African Studies.
Quite possible. I've found National Archives catalogue entries where 'C' has appeared for both 'O' and 'G'. This from Wiki also fits the bill: In September 1939 eligibility was extended to include native officers serving in the Indian States Forces, Frontier Corps and Military Police, and further extended in January 1944 to include native officers and Indian Warrant Officers in the Royal Indian Navy and the Hong Kong and Singapore Royal Artillery, as well as foreign officers, who could be appointed honorary members of the Order.
Thanks for all your help. New member Barjesh Rana appreciates it as well. I have helped him with the service of the 4th Gwalior Infantry, ISF. OBI certainly makes sense.
