Howard, I think you are right, the grub screw is holding the spring pin. This was not an unusal mod in racing circles to enable a quick change of rear axle . One had a selection of complete axles with different ratios. I can’t see a cotter in the hole.
This looks like an Austin Seven axle with Morris backplates.
