Above details taken from Ray Westlake's' book
'British Regiments at Gallipoli' (ISBN 0 85052 511 X) published 1996 by Leo Cooper. You will probably get more information from the book on the 42nd Division mentioned in Laura's thread here

Quite a few of the positions mentioned above will be found on the map below,
* including the 1st & 2nd Australian Lines. I would guess that the 5th Battalion went into these at about the same time as the 6th Battalion LF, which was when they were in 'reserve' in July and August
Looking forward to seeing your photographs in due course.
Good Luck
Michael
