I got a couple of these off ebay in April, 2016 models. They where sold as new but have a R branded on the bottom of the tank. This one I did a gasket delete, put in a pop up piston and removed the baffles in the transfers. Have runs less than a tank through it. Power head only, bar and chain not included. $475+shipping Below are some pics I took when I put the pop up in it. In a few minute I'll take some of the saw and put them up.
