Can anyone identify this RAAF crane

[motto]

The yard at Lia Street, Coober Pedy belongs to a well known local identity named Emilio Chignola. Emilio is an energetic and skilled modifier of machinery to make it do whatever he wants of it. The Studebaker/airfield crane would be an example of his work.
In his time he has acquired and in many cases passed on quite a few ex military vehicles most of which have been abused, dismantled, modified or cannibalised which is the usual fate of any vehicle on the opal fields.
