| -3- Rm{William Robotham - Chief Engineer}/Std.1/JH.18.8.37. (6) The two sample car heaters made up by Marstons were brought back by the writer for test purposes - a rough figure for the price of these heaters is £3.10.0. - £3.15.0. according to the excellence of the motor used. (7) Although Marstons are continuing with experiments on Hydrogen brazing (of the type used on Harrison oil coolers) as and when the furnace is available at Whittan, they said that there is no likelihood of their attempting production of this type of cooler for an output of the order of ours i.e. approx. 12 per week - no other firm in this country is fitting an oil temperature regulator of our type.
