Are you sure about the model numberIJ There was an SP 9 and an SP12 then SP120 and finally the 150 in these Case combines of the early 1950s. They were basically the current pull machines refitted as self propelled machines using Case tractor engines for power. There was also hillside models the 301 and 302 which were versions of the SP 120. The engines were mounted behind the header on the right side of the combine.
