The last serial for the 1962 models was 123699 which makes yours one of the late models. I guess the late 62&#039;s could have been changed to the new appearance. The pictorial book by P.A. Letourneau shows a 1962 Oliver with the checker board grill on p61,62. The tractor has the plastic oval over the grill that spells Oliver. I think about 1963 this plastic oval was replaced by a metal oval with just an Oliver emblem
