It does not appear from my research that Nordstrom ever manufactured small, 1/2" threaded lubricated plug valves. I am thinking it is a company that used to exist but has since been purchased by another company after the above valve was manufactured.
Can someone identify the manufacturer of this older plug valve? The logo or emblem is basically a "N" inside of a square.
