From a bit of research yesterday I think this is called "The L1" LUXO lamp. Wanted to check in, because the one that I saw that was a near match was stamped "Norway". MIne is not, and has a slightly different LUXO stamp. Definitely older from the looks of the "Brotherhood of Electricicans" label. The top fits into the base --base literally weighs over 9 lbs. Any thoughts about this piece or words to describe? Is in an architech's lamp? Thanks.
