Charming stainless steel, brass and cast iron unit. Might be a bit of a project- the piezo starter isn't working (looks like a generic $20 part) but it lights easily with a lighter. I bought it used a few years ago to put into a trailer, but ended up selling the trailer. All I've done with this heater is hook it up to propane to test it. Includes the diffuser, 3' or so curved chimney, roof cap, propane tank adapter and extension hose. Similar units seem to sell for $450-$600 new.
