Quote: Hercules Grytpype Thynne @ 18th July 2022, 8:24 AMI may well have mentioned this before, but in 1976 (remembered well, especially trying to keep out new born baby son cool at home), we had a repair workshop at the back of our photographic retail and in the winter we used a Super Ser portable gas heater (do they still make them?) and in a mad moment I suggested we close all the doors, put all three burners on full blast and see which one of the three of us was the first to run out of the room, unable to stand the heat any more!
Pleasures were hard to come by in those days...................
I do have a Super Ser gas heater in the shed so if I'm feeling suicidal I might try and recreate your 1976 insanity later.
