Thanks for the great review Graham. Just a note, the slouch hat worn by New Zealanders during the Gallipoli campaign is there, part 19, pic 8. The hat was (is) the same for both Australia and New Zealand, just the way of wearing it differs. Australia, brim up on the left-hand side with the badge on the upturn, New Zealand, brim down with the badge at the front. The 'Lemon Squeezer' style of wearing the slouch hat was not adopted by the NZ Army until after the Gallipoli campaign.
Cheers
David
