I came across this picture whilst researching my jeep which was known to have been used at Woomera as part of the Long Range Weapons Project in the late 40's and early 50's. Nothing definitive on the jeep unfortunately (no ARN visible) but there is what appears to be a CMP in front of the jeep behind the rocket. Also what appears to be a generator or workshop trailer.
