Interesting! Note the modifications.
The 2 prototypes were in fact based on the C8A, which makes sense as that chassis is lighter and smaller than the C15A. Attachment 134685 |

And despite being based on the C8A, it can carry 2240lbs; a whopping 20cwt!

Based on the width of frame, section modulus, kicked up profile of the frame rails over the rear axle and the length of the springs (also number of leafs to the spring) all matching the C8A I suggest a complete C8AX frame mey have been used in order to have mounts for the cab as the C8A HU seies used different body mounting system for the one piece cab and rear body compared to the sepatate components used on most other CMPs. Another similarity to the C8A is the transfer case mounted parking brake. A)lthough it could be fitted to the C15A transfer case, I don't think it was a factory fitting. The tyre size also matches C8A, which only makes sense as the profile of the C8A rims was the tapered bead seat rather than the flat bead seat of the heavier trucks (modern tires slide onto the HUP rims easily but can be a challenge on C15A).
Interestingly, the axle ratios don't match those specified for either C8A or C15A. I don't know the ratios for the C8AX. |

I was looking at the AEDB Design Record which gives 5.42 or 5.43 for the C8A...
However, when I look at the C8A-04 parts list earlier C8A are listed as 6-37 ratio (teeth on pinion and ring gears = 6.17 ratio) and later as 7-38 ratio (matches AEDB record). |
yes

The New Zealand C8AX was reclassified as a 15-cwt truck after WW2 without any modifications. The CMP range was generally a bit over engineered for their assigned load classes.
