Good post! But I can see a scenario where the gauge might do as the others
mention, specifically if the tube is pinched so that response is slow both
going up and coming down. I doubt if this happens very often though.
I'm all in favor of cardboard since they quit putting roller blinds in front
of the radiator. Matt B sent me a roller blind, more or less as a pattern.
(It was badly biodegraded!) But I would like to refit my 66 122 wagon with one.
The hard part will be finding a sturdy enough blind with a wooden core that is
narrow enough. The cardboard cores can be cut to length but I am not so sure
about the wooden ones. Also the "stay down" feature would have to be disabled.
