Tractor Dearth and Art Deco

I am amazed at the dearth of information on certain tractors and their manufacturers. As a librarian, I have access to many of the finest information sources in the world. I can search millions of books, articles, videos and other publications in a matter of minutes. Why is there so little written on a line of tractors that were in existence for nearly 20 years? Especially since it entailed such an interesting foray into equipment manufacturing and sales by a farmer cooperative (a sort of socialist democracy about which much has been written). I am thinking about publishing a Wikipedia article containing what is known.
Tractors from the mid 30's to the late 50's had possessed a convivial nature that tractors before or since have not had. The stylized Art Deco shapes that permeated the production of architecture, automobiles and art of the period left a mark on these machines as well. The Cockshutt line of the 40's and 50's remain my favorites in this regard. In speaking of art deco, we have to tip our hat to the short lived art work the David Bradley (top).
