You can usually find old SeaSwing stoves in consignment shops. I believe
Bacons has some. Probably most of the others. Make certain you get the
mounting bracket.

SeaSwing stoves will run on Sterno,but reportedly run much better if you have
the Sterno chimney. The stove will take a Primus burner, either alcohol or
kero.

I found a SeaSwing brand new in an antique store.
