Anthony, The B707's used by QANTAS were a mixture of B707-100's and B707-300 series aircraft. The B707's the RAAF bought from QANTAS in the 1970's were 300 models for example. Captain sim's representation of a QANTAS B707-300 is perfectly accurate.

Yes, you are quite right about the 707-320's.

But the 707-138 was a custom built short bodied aircraft for Qantas. And I want one  ;D.

Here is a nice link to an article about the 707 family which makes interesting reading:
