I used to get their receptacles from the now-defunct Fairway Electric Supply. I always considered them to be pretty high-quality. I have quite a few of them installed and have not noticed any unusual failure rates. I even have their devices installed in my own house.
I don't think that they are still being made. I remember them being a big-time manufacturer of porcelain keyless lampholders until other manufacturers started making them out of phenolic plastic. After that, I think Paulding went by the wayside, possibly back in the late 1980's?
