I am pretty sure that it is black. My uncle bought the 1949 Model M used when I was about 7 or 8 years old and it was black and I feel pretty confident that it was the original seat. Not gospel but I would say 99% sure. I now own the tractor and he put a car bucket seat on it about 20 years ago to make it a little more comfortable but is is now worn out and needs replaced with something. Hope this helps
