description and a drawing...

So all of the articles agree on a couple of points, and appear to have
obtained the same photo for publication. However the Magnus Effect, while
well known to be true to every golfer (usually in a detrimental way)
appears
to be backward in some sense.

For the moment, this appears to have moved from my Solved Problems List to
my Unsolved Problems List.

Dunno, looked OK to me. If the ball is flying across your screen from right
to left think of an airfoil moving from right to left, low pressure on top,
circulation has to be clockwise in this view to accelrate the flow across
the top and decelerate it around the bottom -

"1877, British scientist P.G. Tait learned that a ball, driven with a spin
about a horizontal axis with the top of the ball coming toward the golfer
produces a lifting force. This type of spin is know as a backspin."

That would be clockwise in a view where the ball is moving from right to
left...

Note: Have you ever seen a drawing or wind tunnel picture where the object
was traveling from left to right or the air was moving from right to left?
How did we become so consistant?
