One "Whirling Dervish" 2-3/4" stake sprinkler, patented by Comet in 1957. All plastic body on an aluminum stake=no rust. Actually has a rather "beastly" circular spray, maybe 6'-8' in height, 15'-20' in diameter. Water sprays out in a roughly 45 degree angle. Has not been run over by the mower and includes a new hose washer! Excellent condition!
