I'm not sure of its age. It is cast iron and might be 40 years old, or so.
It needs some repair, but I suspect that a collector might be able to restore it to working order. I'm not a collector and know very little about this unit. It would be helpful if I could view some older units to identify the one I'm looking at. I would then try to find its approximate value.
