Free Smelting Furnaces

Somewhere in the distant mists of time I obtained two propane-type smelting furnaces, thinking I was going to get into metal casting in a bigger way than I have.  I now have no expectation of this, instead focusing on smaller castings using my electric smelting furnace.  These two have simply become space eaters and I just want them gone from taking up space that is more valuable for storing yard equipment and firewood.  If you want them or know anyone who does, just let me know.
These do not have burner nozzles nor the requisite plumbing but that is pretty straightforward AFAIK.
