A little late to this discussion, but I have some photos to add to the catalog listing.

This is the 1959 SWF WMK 1-20/34F shepherds crook arm, still in the original packaging.

These are the blades to fit that arm:

And this shows three types of SWF blade attachments, the ones with the setscrew, the ones shown above, and the later blades that use the small clips.

Joris, did you ever locate the second SWF catalog? It would be very interesting to know when the wiper arms with the spring clips were introduced.

Dave, is the wiper arm yours?
If so, could you please post some pictures of the base, and the entire arm?

Thanks...

The trouble with the 356A wipers, no matter which arm is used, is that the drive shaft is too small and soft. The first time the wiper arm is installed, the set screw digs into the shaft. Years later, when you would like to reposition the arm slightly, you can't. A fix would be to spline the end of a harder shaft, put a splined hub on, and modify the arm for the larger hub. Or to modify the gearbox shaft bearing for a larger shaft... Until somebody comes up with a service to modify the gearboxes, and the arms, the A wipers will remain mostly cosmetic. Porsche solved that problem with the C of course.

Note that this blade has an R stamped in the shepherds crook, on the inside of the blade, and the label says rechts (right).

Here are some pictures that show the shepherd's crook arm next to a later arm that is on my D. I don't know if the later arm is SWF or aftermarket, but it has the square corners at the base. It takes wiper blades with metal clips. It is also 5mm shorter than the shepherds crook arm. It is also interesting that the later arm is curved instead of bent. I would like to find another shepherds crook arm to complete the set.

What is the difference between the "L" left and "R" right arms?
