Needs a little work
At some time in the last 39 years this poor dynohub was left in a axle-deep puddle (or the bicycle it was attached to was left out in the rain) for a considerable period of time. When it finally came into my possession, it was seized solidly shut, and I had to apply copious amounts of cleaning oil before the stator unlocked itself from the field magnets.
The stator is going to have to be cleaned with a wire brush, steel wool, and some sort of non-solvent cleaning solution. But before I do that I’m going to have to fabricate a keeper bar to fit between all of the poles of the field magnet, because S-A dynohubs use an iron field magnet which loses its power just like that if you don’t have something ferrous keeping the poles apart.
I’ll get around to it in a month or so (unless I inherit a CNC mill or a big old industrial lathe.)

Cool, David! Look forward to the progress. April has an old S-A Dynohub on her 1961 Raleigh. It got built into a more modern rim (Sunrims CR18 aluminum) in the antiquated 650A wheel size.
