Other than what is printed on the pump I can't find out much about Butlers let alone this model #. I would like to narrow down the age. I'm old and it is older than I am. Are there websites or books that I can get information from? How long this model was available etc. Just any information I can get. Thanks
I have seen pictures of 71's and they look very similar but can't find our anything about the 84. I appreciate your help and estimating the age. Did they ever sell sample pumps? That isn't the correct term but the family didn't have much money at all and their operation was small.
