It's not a Dearborn as already mentioned, it's a Ferguson-Sherman. Get a rag with a little gas and see if you can rub off the gray paint on the tag to see the model number. Dearborn was the new distribution company for the new 8N in July 1947 and all of the implements to go with it after the Ferguson split. This plow is correct for 9Ns and 2Ns. It will work on an 8N as well. Ferguson Equipment was dark gray like the 9N and 2N tractors as shown. All Dearborn Equipment was 8N Vermilion Red.
