Australian CGT mystery

However the predecessor 2-pounder Portees were officially rated ab initio as '30 cwt.' trucks, and yet they were basically the CGT chassis and Oshawa Plant even allocated them the same 8440 Model Number, unlike the C8AX. The evidence suggests that the Portees were built as batches with CGTS. Given the lack of a parts book to tell the difference 'by the book', I extrapolated that the CGT was a 30-cwt. truck therefore. Going one step further, the FGT was as well.

I know we have been down this road before ....

David, WHICH portees were officially rated as 30cwt portees? The 2pdr portees built on a C30/F30 truck (GM model 8441) or the portees with the type 42 cab on a CGT chassis(GM Model 8440)? I can understand the C30/F30 portees being rated as 30cwt because they are a 30cwt truck (!), but does your official reference also relate to the CGT chassis portee?
When comparing the components on the Ford F-GT, F60 and F15A, we found that the F-GT had the chassis rails of the F15A, but the suspension and drivetrain of the F60. The C-GT based portee may have been rated at 15cwt and later upgraded to use a 30cwt truck to make use of the longer wheelbase and the ability to carry more stores.
