Large oxygen cylinder with cap, I believe it's the 250 size. In great shape I suppose it could use a new paint job, but no dings or dents. Central Welding says new ones go for $359 + tax and that is empty. If I recall, there's still some oxygen left in this one, but I can't guarantee it. Cylinder is an easy access for loading and I can help load. Pick up would be at my house in Duvall.
