A point of interest...Colin's file notes the language "Urdu" (an Indian language)
From FIBIS
http://www.rootschat.com/links/01jrd/Military records - Indian Army Regiments: Indian Army Reserve of Officers (I.A.R.O.)
Serial Number: 2499
Date of Rank & Appointment: 10 January 1917
Surname: SEALE
First Names: Colin Ian
British Regiment with which trained : Officers Training School, Ambala
Previous Service : 2 years, Royal Field Artillery Gunner. Educated in India. Engineer, Jhansi
*From Army records previous service was 1905-1907 (when Colin bought his discharge) so looks like Colin rejoined as I.A.R.O.Languages:
Urdu Also noting that Colin Ian SEALE and George Arnold Frederick HEYNE were both I.A.R.O. (Indian Army Reserve Officers)
George Arnold Frederick HEYNE was born 22 Sep 1880
https://familysearch.org/ark:/61903/1:1:FGHC-YJY but fudged date on Australian Army records to 22/9/1889
Colin SEALE was born 2/9/1889
Pondering if George Arnold Frederick HEYNE was the "tutor" as he was in reality 9 years older? Or maybe they were mates as he may have fudged his Indian records as well to 1889.
