Had these given to me this weekend by one of my roommates from college. He had them given to him by his uncle who grew up in Ontario. As a boy he liked to go to farm shows and the big plowing match they have up there and whenever he did he would come home with an arm full of brochures. My buddy is a JI Case guy so he picked out the stuff that was of interest to him and gave these to me. Lots of cool pictures of off the wall stuff you don't normally see. For instance I never knew White offered it but in the Better Farming book there are pictures and specs for a White traveling irrigation system. In the 1975 White full line book there are pictures of a White feed grinder/mixer. I thought they had discontinued those when they dropped the rest of the hay line. Lots of good stuff! I suppose ther isn't much difference between these and the Oliver brochures except every place that would have referenced the US or a region there of, has been changed to Canada.
