This iconic hippie era swag lamp was made by Johnson Industries, the original inventor. They called it a Rainlamp due to the use of mineral oil dripping down the diagonal monofilament strings to simulate falling rain. This is the model 880 in "weathered brass", shown on the cover of Johnson's 1970s Rainlamps catalog.
The lamp is about 38 inches high by 14" diameter. The center Venus or goddess figure in the center is surrounded by artificial plastic fern greenery. It comes with a working green light bulb. The original UL and Johnson labels are still attached to the interior roof, included one listing the serial number.
The lamp was wrapped in heavy plastic bags and stored in a big box when I purchased it at an estate auction in 2017. It was very clean with no damage and the oil had obviously been drained. I was able to drain a few drops more over the course of several days by tilting it diagonally in the box so that the oil fell onto the box bottom, not into the top of the lamp. I then thoroughly cleaned everything I could reach or remove. I was unable to figure out how to access the bottom reservoir where the motor and pump are - the carved wood-like rings around the top and bottom exterior are covering up the screws. I didn't attempt to remove the rings for fear of breaking them. However, when the lamp is plugged in, I can hear the motor humming very softly and evenly with no catching or grinding and it doesn't exude any oil. I didn't notice any scratches, dents, or damage to the lamp.
If I were thinking about purchasing this lamp, I'd be very concerned about shipping damage. So I've added several photos showing how I packed it up: lining the bottom with lots of paper towels in case of any residual oil, wrapping the entire lamp in layers of blank white newsprint, then wrapping in big sheets of plastic encased thick padding. The ferns, light bulb (encased in foam), and chained cord are at the top, over which more thick padding is placed. Nothing in the box can move, so I'm confident it will arrive safely unless it falls out of an airplane.
