We agree that as regards efficiency there is little to choose between a foot and a hand pump. Personally we should always use a foot pump, as we consider this easier to operate than the hand pump. However, if Sales have had no objections to raise to the use of a handpump on the Bentley, we should recommend that it should be used on the 20/25.
