THIS TABLE LAMP is tested… The best research tells me that this is a Palmer product.. If you look at the switch and the plug! I don’t believe this thing was ever used other than by my testing it? If it was used at all some little old lady had it in a corner in her parlor and she never sat in the chair which it flanked. I cannot find another unit like this anywhere online or in requested references.. There are other Palmer products.. But no one has this one.
