Gentlemen, We are pleased to tell you that we have now had your "Boilerine" Tablets under observation during the last six months, and we can emphatically recommend them for use in the Water Jackets on internal combustion Engines. They are especially valuable for use in connection with a modern design of engine, such as the "Dorman" Type 4.K.N.O., where aluminium is used for the Cylinder Water Jackets. Your Tablets undoubtedly prevent the white deposit which otherwise would form, due to the action of water on aluminium. We have not found any detrimental effect, and, in fact, we can highly recommend these Tablets for the purpose outlined above. Yours faithfully, W H.{Arthur M. Hanbury - Head Complaints} DORMAN & CO., Limited, [Signature] Managing Director. | ||
