Unstyled John Deere B 1938

Looking to confirm just what color the radiator/engine fan is proper on the Unstyled John Deere B 1938. I have seen photos with green and some with yellow. Any feedback would be greatly appreciated! Thanks.

Here is my take on it from an earlier post:
I had always heard this about the fan blades being yellow on the back so that's the way I did my 34 A and 35 B. Some people a different shows challenged me about this so I dug into it a little bit to try a find some documentation and or experienced, knowledgeable opinions. Here is what I found:
1-In Wes Malcolm's book A Specialized Look into the Unstyled Model A he states: "The back side of all original fan blades was painted yellow (with a brush) while the front and the hub were green".
2-Green Magazine's Mr. Thinker was asked about this on a model H and his reply was: "Fans were painted yellow on the unstyled tractors and the styled through the 1940 model year, which on an "H" would be serial number 20614."
3-In the Deere Field Service Bulletin #80-S, dated Dec.15, 1937 there is a picture of a model B that shows the fan. It is a black and white picture but you can tell that the back of the fan blades are the same, light color as the wheels. They are clearly not the same dark color of the green parts of the tractor.
I could not find any documentation that contradicted the above.
So, until I see something conclusive that contradicts the above I feel pretty confident about the fan blades on my unstyled tractors being yellow.

I brush painted mine (1938 Unstyled Long Frame B) yellow and the correct police can kiss my grits if they dont like it lol........
