Australian CGT mystery

[David_Hayward (RIP)]

These are the two known data plates off 2-pounder Portees:

GENERAL MOTORS OF CANADA
MADE IN GM CANADA
OSHAWA WALKERVILLE REGINA
MODEL 84-40
SERIAL 1844031433
ENGINE 3757180 BODY SERIAL blank [? WAS THERE ONE?]
TRIM XR PAINT F.C.98

GENERAL MOTORS OF CANADA
MADE IN GM CANADA
OSHAWA WALKERVILLE REGINA

ENGINE 3742886 BODY SERIAL blank [? WAS THERE ONE?]
TRIM XR PAINT F.C.98

S/M 2028
MFD. Nov 21 1941


Compare with C-GT # 12 Cab:

GENERAL MOTORS OF CANADA

OSHAWA WALKERVILLE REGINA
MODEL 84-40

ENGINE 3742940 BODY SERIAL 2478

Then we have the later plate design:

VEHICLE MODEL C60441-M-FAT-4

CHASSIS MODEL C60441-M-W
CAB MODEL 13
CHASSIS SERIAL 3844033748
ENGINE SERIAL PR 3971863
ORDER NO. LV 1798
DATE OF MFG APR 7-44

VEHICLE MODEL C60441-M-FAT-4

CHASSIS MODEL C-60441-M-W
CAB 13
CHASSIS SERIAL 3844031469
ENGINE PR3947470
ORDER NUMBER LV1798
DATE OF MFG FEB 23-44
PUBLICATIONS TAG: C-60441-FAT-4 and MAINTENANCE MANUAL TAG: C-GT-02 MB-02.


and using the DND's nomenclature, that makes the 1943-4 Model CGTs a 3-tonner! Now, why did I not think of checking the designation before??? I have yet to find plates off 1940, 1941 and 1942 CGTs.
