Greg ,
Coming from an area where they cast bells , I found that your comment rang a bell (sorry) about casting techniques .
It does look very like a bell casting , and perhaps the same technique was used to make them .
That is , the usual sand , clay , and horse manure or cow manure hand made mould in a pit , the bell shape being cast this way to avoid cooling cracks . There may be more than you thought to what you said .
I wonder if they also put the finished item on a bell tuner to cut the edge for the top ring . Occasionally , one of those would go into resonance as they skimmed the bell , and the sound started to increase in volume with a wo-wo-wo-wo sound gradually making folks look uncomfortable , but the skimmer simply adjusted the cut to stop the noise . The low pitched noise made the groin area vibrate , making some people pee themselves .
As a youngster , I learned more stories like that about the engineering world than I learned about engineering . But by golly , show an interest and those blokes would take you all round the factory to make sure you saw it all . I actually made a chain link when I was about nine , and did a horseshoe blank about the same time .
‘elf an’ safertee weren’t around then .
So , where were these stoves made , were they cast or rolled , and are they for cooking and heating ? Did they actually “spoil” the crew with these ? I bet that’s what the accountants thought when they saw the price .
