I really don't know whats so confidential about this book, it just has CASE and all the competitors specs side by side for comparison. There is not a pic of a 2090 in the book. If you look at the 2090 pic they do show, the muffler tells me its a 2290. It does have the Neb. test for all 90 series in it, Interesting reading about all the other 30 yr old "new" tractors. I hope the pics of pages are readable. Rod.
