Variation in Ball Weight

Playing Harverson at Leicester Square Reece complained of one of the balls, which, on being scaled, was found to vary from the other in weight. However, he decided to go on with it and at once made a, 538 break. Next day he complained again and the balls were changed. Then he settled down with the new balls and made a 333 break, or a majority of 205 in favour of the worse set.
