I have been looking into 70s vacuum a bit more heavily, and I have hit a wall with central vacs. We didn't get central vacs at that point, though I know there were some pretty cool machines. I have watched all the Owen Perkins videos (literally all of them, even though I already have in the past) to get up to date on Thomas, Beamco, Nutone, Walvac, Cleanmaster, Vacuflo, Vacumaid and Filtex. Beyond that, I can't find much. It might be the internet thinking I don't care about American stuff, because I am in NZ, though I don't know. Any help would be appreciated.
