As far as I'm aware Terne Plate is still available from specialist steel stockholders.
Yupp, thats it Jeff, so the joints were just sweated together to form a perfect seal, and as you say to help prevent corrosion, to a degree.... Its not cheap sheet anymore, due to the cost of base materials, but quite nice to work with...
