Look at this thing!
Someone gave me this, all plastered with blanket insulation of some kind (should have taken a picture, but didn't; I was too concerned with taking it off). At first I thought it was made of steel, because a magnet stuck to it, but it turned out that the magnet was sticking to the steel mesh that was part of the insulation. Turns out that this is an amazing silver-brazed copper boiler, complete with water cross-tubes in the flue, superheater, and GOK what else.
Here's how it looks just now: bare of insulation, broken sight glass removed, all valves and fittings freed up and moving nicely.
It looks like a very old boiler, as you can see from the wooden valve wheels. Nonetheless, so far it looks very solid. I'll have to make blanking plugs, etc. and give it a pressure test, but at the very least it makes a dandy paperweight!
