The particular model I'd like to get is quite old, ca 1970-75
The one on kijiji seems somewhat recent looks more plastic or something, whereas the old model was all-metal (including the nice little lids, surrounded as i can remember by a thin gray-colored rubber 'gasket')
Thanks again {) (I do not despair, but know it is rare)
I'm also looking to find the very old Hoover twinnie my mom had - model 0500 produced circa 1965 (as much as old as I !!)
