I am trying to track down a vacuum that both of my grandparents had in the 80' and early 90's, it was a Eureka wide path upright, it may have been called "Sampson" but I am not sure about that. I think the model number is 4040 but am not sure. Both of my grandparents had one one's was green and tan an the other's was brown and tan. Can anyone help me out and Identify this or does anyone have any pictures?
