As I began taking apart my Stuart steam plant I began to wonder if the boiler was unfired even though at first glance it appears rusty and dirty. Previously I would have guessed the copper boiler was unfired as it is really clean with no soot or blackening but then why would someone go to that trouble and put it back in a rusty boiler body? The sight glass doesn't show any signs of mineral deposits and I can't see anything inside either but there are slight deposits on one of the bushes. I've sold boilers before as "unfired" that looked similar and wouldn't want to ever lie about condition. Any thoughts?

A bix burner would leave it pretty clean, the picture looks like the sight glass has some deposits in it...could be the lighting. I would probably list it as "lightly used."
Just be aware, some of the older Stuart boilers have Asbestos in them. I ran into one like that not long ago. I love those 504 Babcock boilers!
