A large multi-tube copper boiler, silver-soldered copper construction, very substantially made with rolled barrel and coppersmiths joint down the seam. Stamped "Solent Steam Services" at the bottom with initial hydraulic test of 220psi - it's just had a hydraulic i test in the workshop and is in first class order.
Designed for coal-firing, it is currently missing a grate, although a fabricated stainless steel item would be easy to knock up and would last pretty much forever.
