There are more than enough cast iron 'CON FOR PRIMUS' trivets around. They were made by Condrup in their capacity as UK Primus import agents.

Certainly different Ian, and very well preserved. Stating the obvious but they can't have made many of this type if survival rates are to be taken as evidence.
