Dear Sirs, "ALL'S WELL" Anti Freezing Compound. ------------------------------------ We should like to draw your special attention to this compound, which we have just placed on the market for use in motor radiators. The pamphlet enclosed will give you the requisite information as to use, but we should like to emphasise the value of the preparation in radiators in all classes of motor vehicles, which consequently should be of considerable interest to you. The points particularly to be noted are, 1. Only one filling per season is necessary to safeguard the radiator against frost. Any loss due to evaporation will only need to be made up by the addition of water. 2. It will not be necessary during the whole of the winter season, to draw off radiator as a safeguard against freezing. 3. A mixture of one-third compound and two-thirds ordinary tap water will withstand 25° of frost, is completely miscible, and no decomposition or precipitation takes place at any time during use. 4. The cooling value of the mixture (compound and water) is equal to ordinary water. If there are any other points you would like us to discuss, we should be only too pleased to do so. We are prepared to quote you the following special prices, viz:- 1 gallon cans ............ 16/- per gln. 2 " " ............ 14/6 " " 5 " drums ............ 12/- " " 10 " " ............ 11/6 " " 50 " steel barrels .... 9/6d.
