CAR RADIATORS. +3486 In August or September it will be possible for us to buy in England the Harrison Vee Bonded Core radiator matrix. We have tested this type of radiator matrix thoroughly and hope to introduce it on to all our cars as early as possible. Owing to the large increase in efficiency given by this matrix, we shall be able to reduce the thickness of our matrices and save in weight considerably. At our request BY's Dept. have given us details of radiator parts suitable for a 58 mm. matrix on the 20/25 HP. car and for an 84 mm. matrix on the Phantom. These details, however, still retain the cut away corners and tunnel for the thermostat operating levers, and for this reason we are not proceeding with them. The Harrison type matrix cannot easily be made in shapes other than a straight sided square cornered shape, and we think it well worth while to look into the possibilities of altering our top and bottom tanks to achieve this object. Marstons are laying down plant purely as the result of our tests on this radiator matrix, and we naturally want to take advantage of the benefits attained as early as possible. 'E' Dept. is already aware of our requirements in this matter, and we think it should be pushed forward as an urgent job. For the Bentley we shall use a 58 mm. matrix; this is already a good manufacturing shape so that no alterations will be required apart from those necessary due to the thinner matrix. Actually we shall save nearly 30 lbs. in weight on the Bentley radiator by using this matrix. Ha/Lid.{A. J. Lidsey} | ||
