21st Infantry Bde, 7th Australian Division markings

[Larry Hayward]

I'm looking for examples of the markings used by 21st Infantry Brigade of the 7th Australian Division at Balikpapan in July 1945 and in particular those of the 2/14 Battalion and the 2/27 Battalion that landed at Sepinggang airstrip with a CAV unit (Cavalry?).

Also does anyone know which of the following RAE units supported the 21st Brigade;

Divisional Engineers 2/4 Field Company
2/5 Field Company
2/6 Field Company
2/9 Field Company
2/25 Field Park Company

My dad recovered a Chev C60 Derrick (A frame type), a Dodge Weapons Carrier and a few Jeeps off the beach a few months after the battle and I fancy doing a model of each. While the Dodge and the Jeeps could have been used by any of the above the Derrick is a bit more specific to the Engineers.

I know the 7th used a Kookaburra on a boomerang as the Div sign but some accounts say that the bird was more detailed than just a white silhouette and that by 1945 Army boots had been added to the bird's feet!

Not much available on the web so any help gratefully received.
