You are right, it was a non headlight model and I don't remember ever seeing vint using it, it was always Thelma vacuuming with exception of the one where her cousin Lydia came to visit and Iola was vacuuming with a turquise Eureka upright also in mint condition as were all of her other vacuums shown through the series.
I also remember Alice vacuuming on the Brady Bunch with her Convertible 1020 I liked that because it is the same as Grandmas Convertible
