Dear Sirs, We are requiring a car heater for one of our Ph.III. cars, and would like to use either a Harrison Twinflow Heater of the type which you have already supplied to us, or a heater of the type which was fitted to one of our experimental cars, and obtained from yourselves by our Mr.Honeyman of our Sales Department. This heater we believe is known as the Delco Heater and is assembled by yourselves - we would like to receive any information which you could let us have regarding weight, price, BTh.Vs{J. Vickers}/minute dissipated, air flow etc. It would greatly assist us to decide which heater of the two (the Harrison or the Delco) is most suitable for the car in question if you could forward one of each type of heater to us for our examination (together with the technical information mentioned above. We would then send you an official order for the heater chosen and return the other one to you. If you could send these heaters by return, it would be greatly appreciated.
