Mario,
OK thanks for the king pin info . I think the CV 11/40 is a civilian model truck , it first appeared in late 1937 or 38 along with the other CV range of trucks . I have the Harry Edwards book here somewhere , I will check that . And, I thought the CS8 king pin has a straight pin , not stepped ? The 8 cwt PU does use a stepped king pin .
Yes I would like the contact details for John Walker .
