Mike,

I have no evidence whatsoever our tugs were operated by the RAAF just weight of probability.

If they were from American delivered serial numbers you would have to conclude they were American stocks left here (whether used by the RAAF or sold to civilians directly).

Being British 1941 delivered tugs and both ours so close in serial numbers I would assume they were issued to the RAAF somewhere - most probably Middle East. The photo of the RAAF operated tug in Libya adds some possibility these two and others were brought back to Australia from there. Maybe they were handed to the Australians in the Japan Occupation Force or Korea or Malaya?
As you know any equipment picked up by these "deals" might have unit, formation or even theatre records but have absolutely nothing in the armed forces central aquisition records.

To my mind it seems unlikely they were some sort of post war civil import but who knows.
