The Retention Piston Desk Lamp belongs to a 35-piece limited edition that features hand-engraved numbering at the bottom of the lamp. For authenticity, the lamp is marked with a Flying Monkey stamp. This adjustable lamp with modern art design is made from a vintage retention nut and piston from a Cessna 182 Skylane airplane propeller. The lamp stands approximately 21" tall and comes with a 6-foot cord and a 40-watt bulb. The stunning accent piece has a lamp base that has been buffed to a mirror-like luster.
