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

[Phil Waterman]

There are a couple of other differences, take a look at the General Specifications and Data pages in the manual as you read down the lines you will see that the following:
• C30 are listed as being 134” WB and there is no 158”WB C60
• Axle track for C30 is ½ narrower then the C60
• Number of springs C30 rear 12 leaves with no auxiliary springs C60 18 leaves with auxiliary
• It also appears that the C30 may not have been equipped with winches while C60 this is a regular option

• There are also some differences between the C60 that are equipped with the 16” rims have smaller brake drums, this I discovered when I went to swap tires and rims between my 1941 Pattern 12 C60L and my 1942 Pattern 13 C60S the brake drums are smaller.

• From the service notes it also appears that the C30 shared the smaller front steering knuckle
