| 1158. S/W. {Sales / Derby Works} (Rm {William Robotham - Chief Engineer} /Std.) STEADMAN - Hn. {F. C. Honeyman - Retail orders} 6/MK.1.2.37. Heaters. With further reference to Rm {William Robotham - Chief Engineer} /Std.15/AP.26.1.37, the Delco people tell us that the heater on 38-EX (1) weighs, without fittings, 3 lbs. 5 ozs., (2) retails at £4 and is subject to a trade discount of 20%, (3) gives a standard output of 1,100 B.T.U. If you have the opportunity, we would recommend checking the weight as it seems to us to be light. Hn. {F. C. Honeyman - Retail orders} | ||
