X.4300 We had a visit from a representative of the Arc & General Equipment Co., who sent us this heater for test, and he was very anxious to find out how the test was getting on, and what we thought of the thing generally. I should like to know whether you would be able to make a report, or whether you think there is any likelihood of the heater being fitted to some car.
