This is the Italeri 1/48 Bell 47 Sioux
that Ralph modified to represent the Australian Army aircraft
as flown in Vietnam. Ralph tried to make a "generic" Viet
Nam base with some red dirt and a few different "grasses" from
the blended turf 'stuff'. From the pictures it came
up looking ok as the grass bits have ended up sitting proud
of the dirt so it has some scale 3-d relief.
The Roo's on the aircraft have a different angle to them
but Ralph used photos taken in Viet Nam as references and
is a little perplexed as all other squadron machines
have them on the normal "horizontal" way.
