Frank. I think you and I are talking about two differet styles of decals.The first ones were white. They were used untill late 60 early 61 if memory serves me correctly. The oval emblem was also green. Then the black, small block letter type decals and the smooth rear hood sides were introduced. This is probably when they started with the red oval in the grill. Then you have the Cockshutt type decals. The first tractors we had the Cockshutt decals were the new B model 1800&#039;s in the fall of 62. They do not say Oliver diesel on the manifolds either. Don&#039;t forget the later 770&#039;s do not Say Oliver Rowcrop on the axles either.
