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

[David_Hayward (RIP)]

Very interesting information! This is the first documentary info I have seen on the 2-pounder Portees: Chevrolet and Morris-Commercial.

This is a photo of the 2-pounder Chevrolet Portee based on the Chevrolet Gun Tractor which we now accept, I hope, was a 3-tonner chassis although it did not carry a load. This version was officially a 30-cwt. Can anyone confirm please which size wheels they are?
