According to the Massey books that machine is an 86, that is by serial number. I do not know if the break on extension and auger color was somewhere in 86 or what the story is there. It is my understanding that the 87 machines do not say massey ferguson, just masseyIJIJ. we bought that machine with about a 1000 hours and to the best of my knowledge, it is original, maybe some one else can shed some light on this. Thank you for looking. Brad
