How do you differentiate between a 30 cwt and 3- ton

[David_Hayward (RIP)]

This was the ill-fated 6-Pounder Portee based on Chevrolet C60L chassis, although these were rebuilt to 3-tonner G/S trucks. The Chevrolet 2-pouder chassis were rebuilt to G/S lorries, 17-pounder tractors, or sold to the New Zealand Government. I suspect that the 6-pounder tractors were MCC C8/MG Portees, some of which were converted to tractors, others to G/S lorries I think, and some sold to the NZ Government!
