| N-W. X3563 Br2/H.24.8.21. Technical - Thermostat Fittings. X3563 -------------------------------------- I have received several criticisms from owners and drivers of cars fitted with the thermostat system of water circulation, in which they say it appears a great pity that we have now discarded the thermometer, as there is of course nothing to denote if the thermostat is functioning correctly. I therefore consider it worth while to put this criticism forward. Incidentally, I would add that we are fitting thermostats to various post-war models which had originally been delivered without the thermostat, and these have the advantage of having the thermometer, which was of course originally supplied.
