Hey everyone, I'm wondering if those familiar with some history from these manufacturers could provide some information, surprisingly, there's really not a lot of information from a google search. First, I would like to know more about the canister vacuums made by Eureka between the 1950's and the 1970's or 1980's. I know they came out with the canned ham series of canisters, and I think eventually there was a version of that vacuum that used a power nozzle. There were two other canister series that Eureka made, and I can't remember what they were called, but, what was unique about each of the three different series? The vacuum museum has a canned ham from the 1950's, love that vacuum, it has an excellent sounding motor. Now, regarding Kenmore vacuums. I know in the 1970's was when some of the best Kenmore canisters were produced. Does anyone know how many different models there were in the 70's? Did Sears release new models each year or did each model have a run for a few years the way the Electrolux vacuums did? I've thought about maybe trying to acquire some Kenmore models from the 70's, but don't know what models to look for. Are bags even available for any of those older Kenmore and Eureka canisters? I would really love to know more about the older canisters from these brands.
