A US Army Cast Iron Cannon Heater model #18. These were made from the Civil War until the end of WW2 for the US Army. This one is the middle size heater and it will burn wood or coal. This Heater is complete and in very good original condition without any cracks or broken pieces but the grate is sagging a bit. It probably weighs about 350 pounds. I'm listing this for an old friend who only has a land line. Phone calls only.
