Taylor, in Taylor on Golf, at page 207, says:

Then, as the club comes back in the swing, the weight should be shifted by degrees, quietly and gradually, until when the club has reached its topmost point the whole weight of the body is supported by the right leg, the left foot at this time being turned, and the left knee bent in towards the right leg. Next, as the club is taken back to the horizontal position behind the head, the shoulders should be swung round, although the head must be allowed to remain in the same position with the eyes looking over the left shoulder.

At page 30 of Practical Golf Mr. Walter J. Travis says:

In the upward swing it will be noticed that the body has been turned very freely with the natural transference of weight almost entirely to the right foot, and that the left foot has been pulled up and around on the toe. Without such aid the downward stroke would be lacking in pith. To get the shoulders into the stroke they must first come round in conjunction with the lower part of one's anatomy, smoothly and freely revolving on an axis which may be represented by an imaginary line drawn from the head straight down the back. Otherwise, the arms alone, unassisted to any appreciable extent, are called upon to do the work with material loss of distance.

At page 88 of Golf in the Badminton Series, Mr. Horace G. Hutchinson says:

Now as the club came to the horizontal behind the head, the body will have been allowed to turn, gently, with its weight upon the right foot.

We here have the opinions of five golfers, whose words should undoubtedly carry very great weight. The sum total of their considered opinion is that in the drive at golf the weight at the top of the swing must be on the right leg. I have, however, no hesitation in saying that this idea is fundamentally unsound and calculated to prove a very serious hindrance to anyone attempting to follow it. So far from its being true that the weight of the body is supported by the right foot at the top of the swing, I must say that entirely the opposite is true, and that at the top of the swing the weight of the body is borne by the left foot and leg in any drive of perfect rhythm.

This may possibly be going a little too far, so we shall, in the meantime, content ourselves with absolutely denying that the weight at the top of the swing goes on to the right leg, and with insisting that at the top of a perfectly executed swing the main portion of the weight must be borne by the left foot and leg. In so positively making this statement I am confronted by a mass of authority which would deter many people from essaying to disprove such a well-rooted delusion in connection with the game, but I think that before we have finished with this subject we shall be able to show very good reason for doubting the statements of these eminent players.

There is no possible doubt as to the rooted nature of this belief in the minds of these players. James Braid, in fact, emphasises it in some places. He says in How to Play Golf:

When the swing is well started, that is to say, when the club has been taken a matter of about a couple of feet from the ball, it will become impossible, or at least inconvenient and uncomfortable to keep the feet so firmly planted on the ground as they were when the address was made. It is the left one that wants to move, and consequently at this stage you must allow it to pivot. By this is meant that the heel is raised slightly, and the foot turns over until only the ball of it rests on the ground. Many players pivot on the toe, but I think this is not so safe, and does not preserve the balance so well. When this pivoting begins, the weight is being taken off the left leg and transferred almost entirely to the right, and at the same moment the left knee turns in towards the right toe. The right leg then stiffens a little and the right heel is more firmly than ever planted on the ground.
