Does it seem logical that, IF they had sold so many they were widely popular, that they wopuld have to ask AC to start building them. I could see that from the git go, but not way down the line.
THAT SAID, I do know Bull DID have manufacturing problems. Seems like AC missed the boat by not building the BULLS While they were perfecting their own 3 wheeler, THEN, when they were ready to present it for sale, dropping Bull, That would have cut the legs of a serious competitor, AND AC could have been making money while they were developing their own tractor, not to mention seeing the bugs in the Bull by building it, and not incorporating them into their own tractor. O well. Thanks for the comment.
