I have recently aquired a saw that I have never seen before. The saw is not a chain saw but it is evidently made for cutting firewood. The saw is called Super Rebel Wright Saw Model GS 4520. It is manufactured by Wright Power Saw & Tool Comporation a subsidirary of Thomas Industries Sheboygan, Wisconsin. The Saw is of good size and gold in color. The mechanical part about this saw is that instead of a chain, the teeth on the bar slide back and forth on the botom of the main bar. The main bar is 16" or 18" in length and attached to the body of the saw. The teeth are worked by a piston. I have ran numerous saws in my life but have never seen anything like this. I would like any information or discusion that is out there. Thank you Walter.
