I have just purchased a Massey 860. The owners manual for it has been severely roughed up and mouse eaten before I got it. I would like to get a new one. I have been told they are serial number specific. I am wondering if anyone would know where I would find the serial number so that I can order a new manual? I think it was built around 1983 but I am unsure. It has a silver cab and still runs the 6 cylinder Perkins.
