An just to hijack your thread (a little) - Harris's Westerner on the left, mine on the right. Notice how the fade between dark and light on his is more gradual than on the top of the Wood Dale? On the bottom, the fade on mine goes much higher as you can see by the proximity of it to the bulls nose. The stencil for the longhorn changed slightly as well - Harris's is much sharper in contrast with less overspray. The steer's head is broader as well.
It may just be my monitor, but the colors seem slightly different as well - Harris's with more of a brown tint, mine with more red.
Harris and i concluded that the paint/pattern on mine seems "cruder" (not in a bad way) then his. Clearly these kettles were done by hand and are very individual:
Here is an updated comparison including the Westerner of the "unknown owner" It too, is a Wood Dale (like mine) and yet is very different, especially in the execution of the fades:
