Good afternoon all. I am new to this forum and have a question that I am certain someone here can help with. I have an old Allis Chalmers tractor that I'd really like to know more about. It has been repainted multiple times over the years and it has nothing to tell me what model it is or what year it was built. Just from looking at pics on the net, it looks like an AC B. My dad bought it used around 1972 and used it frequently until his death 8 years ago. I'm hoping someone here could tell me what to look for. Thanks in advance.
