Looking at the photo of the broken off end it seems to me that the cause of the failure may have been a loose taper. Probably a good number of Austin Sevens are rattling around on their key ways and I wonder if the cause of half shaft failure is as well known as perhaps it should be.
I remember reading somewhere that the key way is only there to allow the hub nut to be tightened; the working load is taken by the taper which needs to be fully mated and tight.
If my memory serves me right, half shafts should be replaced in pairs as a mater of course.
