early electric vintage industrial office desk lamp, cast iron metal gooseneck work / task light

1920s vintage all metal desk light with gooseneck, cast iron base. This stands about 15 1/2 tall with the neck in an upright position.

This is in good condition - there's some scratching and spotting to the original finish over the metal, but it's fairly clean overall. The old socket and wiring seem to work just fine!
