I had the next generation of that bought in 75. It was my first big vac purchase from Sears, cost a mint back then and it was my most important one. And if you already haven't heard my lament, when we moved back here in 06 from Alberta I unloaded all my vacs into this new house and it wasn't there. I have no idea to this day where it went. There is no way I left it in the old house, no way, no how. I'd have run thru the burning house to retrieve it.
