I never really installed Paulding devices but maybe once or twice... (I found them once , of all places, at a plumbing supply!) that was somewhere in the mid 80's..

I do remember opening one (screw together outlet) and the contacts and such weren't really any different than, say Levitons resi/light commercial outlet of the era.. In other words... It wasn't Hubbell, but it wasn't made in China either smirk
