NELA TRUTINT LAMP

Yes, we found it in the attic of a house we bought. No kidding. Cliche' I know. I've found a few references on the web. It's a color matching unit that much I know. Made at the NELA Park facility of Edison Electric. I also found mention of it in an electrical journal from 1919 saying it was a 'More elaborate than the previous units" perfect for "High Class Shops". It stands 28" tall and weighs at least ten pounds!
The base is iron and the rest is brass. Still has original wiring and works fine! My wife uses it on her computer desk and loves the thing. Anyone ever seen anything like this? Thanks. Dean E.
