The blades are 260 mm long, as it says on the box label. The box is stamped with the Porsche part number.
The SWF arms are marked L and R accordingly, under the shepherd's crook. There were also RHD wiper arms for Roadsters, so four different versions.
I wonder if the plot thickens. I went to my mechanic's shop today to look for blades. He has a collection of a hundred or so from six decades of working on early Porsches. As we were looking very closely at them, he pointed out that the correct blades have a little plastic collar around the short axle that the shepherd arm hooks onto. In other words, in Jon's first pictures, I think if you try to install the pictured blades on the pictured arms, the crook of the shepherd arm will not firmly grasp the axle- there will be slop.
Here are two pictures of my one (correct?) arm showing the (somewhat cracked) collar.
I do see that Jon's beautiful original box is stamped with the correct part number, but maybe the contents got switched or somehow the collars fell off or were removed.
