I believe you have an 8N. The 9N ended production in 1942. To confirm, look on the left side of the block just behind the oil filter. After the * at the beginning of the S/N, the next 2 characters give the model.
Anyway, yes, loaders were made for both the 9N and 8N. The problem is they don't work very well. Different companies made them but mounting was poor. The tractor also doesn't have adequate brakes or steering for the loader (e.g. no power steering makes it very difficult to turn).
For my 8N, I just put a scoop on the 3-point hitch. Doesn't hold as much as a loader but it worked fine.
