A nice large vintage Rain Bird 95 part circle impact sprinkler. This was the largest part circle impact sprinkler Rain Bird made. These were common before the larger "irrigation guns" took over. It's one of my favorite Rain Bird impacts. It has a 2 inch male NPT connection and three nozzles, I have it fitted with a 5/16" drive nozzle, 13/32" range nozzle and a 1/4" spreader nozzle with an adjustable breakup pin. The sprinkler is operating at 45 PSI and about 126 GPM.
