This is a beauty! It's a brand new Buckner IP101 sprinkler. These impact rotors were built to last and Buckner made some top notch stuff when it was producing sprinklers. This is a combination of brass, bronze and plastic. The nozzle has a diffuser pin which allows for the radius to be reduced. It isn't marked but my best guess is this a 7/32 which puts out a lot of water. It is a part circle sprinkler with an adjustable arc up to 330 degrees. The case is plastic and has a check valve to prevent low head drainage when it is not running. The inlet is 1". If you're a collector, this is a gem. If you have a large field or even a golf course then you know this is the sprinkler for you. This guy us all boxed up and ready to ship.
