| W/S. To Hn.{F. C. Honeyman - Retail orders} from Rm{William Robotham - Chief Engineer}/Std. 1158 Rm{William Robotham - Chief Engineer}/Std.15/AP.26.1.37. We have been collecting comparative car heater performance data etc. and would like to have some particulars of the heater fitted to 38-EX. by Park, Wards & Co. We understand that this heater was supplied by Hn.{F. C. Honeyman - Retail orders} - it is presumably made by the Harrison Radiator Corporation judging by the matrix used. We should like to have any details as to weight, cost, performance etc. which you can let us have. Incidentally, the electric bulb lighting the controlling switch has failed and on examining it we find that it is a 6.V. bulb. Does this mean that the heater motor is also suitable for 6.V. only?- if so of course it is incorrect. Rm{William Robotham - Chief Engineer}/Std. | ||
