There is a fairly comprehensive history on airhistory.org.uk
It was with 2Sq until passed to the RAE on 3.7.14
Then allotted to 1Sq 14.10.14 but passed to 1RAS 20.11.14
Transferred to 10Sq on 7.1.15 and used by ‘A’ Flight at Lydd
A letter from HQ Admin Wing in about March 1915 to Major McInnes in the Directorate of Mil Aeronautics says ‘We have a BE working with the Siege Artly at Lydd, no. 267. No.10 Sq to whom it belongs have now left my Wing and it would be a good thing to re-allot this machine to No.1 RAS who now finds the personnel round there’
