I don't think you're going to get one of the cast-iron shells in the UK
or be able to afford to import one. They make a better job IMO since
they have the doors, control of inlet and exhaust gasses and are simple
to install (place one on the reinforced concrete base then build over it
as is shown in the guide above).
