Hi Quang,
You make an excellent point about the lack of uniformity of Australian military uniforms.
Dress codes were never policed as rigourousy in the AIF as they were in the British Army, much to the annoyance of the British officers who regarded them as colonial ruffians.
The Light Horsemen weren't known for how smartly they looked in uniform and only saluted the officers they liked (which really pissed off the spit and polish Pommy brass), but they were regarded as some of the toughest fighters in the Middle East campaigns.
It's a little known fact of the war that the Australian Light Horse beat Lawrence of Arabia and his Arab Revolt in the race to capture Damascus from the Turks, but were forced to withdraw for "political reasons". The Light Horse (who were actually Mounted Infantry not cavalry) also performed the last successful "cavalry" charge in history when 800 men charged the Turkish lines at Beersheba in Oct 1917. If you get a chance, check out the movie "The Lighthorsemen".
You've done your homework Quang, so well done.
I particularly like the "kangaroo feathers" in his hat.
We Aussies have a weird sense of humour and like calling blokes with red hair nicknames such as "Blue" or "Bluey", "Ginger", "Carrot Top", "Rusty" and "Blood Nut", and I'm sure there are many more.
To me, this bust will always be Bluey, and I'm definitely going to buy him. Thanks for doing such a great job on such an iconic Australian military subject.
Cheers
