The first link shows an early (1940 or 1942) G4112 Model Y or Model Z. The dash has the early civilian gauge cluster, which in late 1941 was changed to standard military gauges. The embossed Chevrolet engine side panels were also eliminated (just the embossing, they still had side panels). It also appears that the pics are mixed together from more than one truck. One of them (not the one with the snow plow) appears to have been a winch truck, as it has the factory frame extensions, and 9 leaf front springs instead of the standard 8 leaf...
