This tractor is the first Case IH 7140 off the assembly line sold to the public. Case IH used this tractor for promotional purposes at farm shows across the US during 1987-88. This tractor was then purchased by a farmer in Nebraska. My customer purchased this tractor at an auction and then proceeded to have the tractor restore by us. With the customer wanting the tractor restored close to original as possible, we used an original piece of sales literature and a neighbor's original Magnum for reference.
