Lucas dynamos are often a source of trouble. But we have most parts to fix them again. Armatures, fieldcoils, brushes and bearings. When ordering armatures,please measure the length and have a good look at the drive end. When you replace all the 50year old parts and wiring and fit an electronic regulator/cut out switch (don't mess with those mechanical nightmares, you're not going to win) and use a fresh battery, it will be reliable for years to come, even at 12Volts. But the capacity remains limited. Try to cut down on power consumption by using LEDs.
At the moment I am moving the shop to a new location.
