Hi Andy,
Here are a couple of photos of story so far. Visiting family have helped me dismantle the old boss which, as you can see from the photo, is still stuck on the crankshaft, and we now have prepared my ebay flywheel to replace it without disturbing the boss, and hence timing.
The next phase is to reinstall the points and check the timing and, if OK, wire in a Kettering type ignition system. This way we abandon the Villiers coil and capacitor, using only the points to time the spark.
Best wishes…… Dave
