Indian Forces in the Persian Gulf

[Quicksilver]

Do any of the members have information on the dress of the Indian Forces that served in Bahrain in World War 2? I require the information for a book about Kuwait, Bahrain, and Qatar. In particular I am interested in any of the following:

• 15th AA Battery, Hong Kong Singapore RA, formed 8 September 1939
• 23rd AA Battery, Hong Kong Singapore RA (HKSRA)
• 2nd Indian (Heavy) Anti-Aircraft Regiment
• Land defence was provided by a company of 3/11th Sikh Regiment
• Air defence detachments came from the 292nd Heavy Anti-Aircraft Battery Royal Artillery, and 247th Light Anti-Aircraft Battery Royal Artillery.
Thanks for reading this,
