Nothing fancy here, just a good old 031AV. These were great firewood saws back in the day, and still make a good reliable saw for a firewood cutter on a budget. This one is complete and runs exceptionally well, possibly due to the fact that the muffler has a loose baffle inside that helps un-restrict the exhaust. I have a near new 16" Rollomatic E bar for it and I will include a good loop of RS chain with the sale. Saw is missing a bar nut in the photos but will ship with two. $150 + shipping from 12566
