Didn’t the Miller dynamo have the regulator in a little pressed tin box on the outside ? Funnily enough I’ve just been asked to look out for one at the next Newark Autojumble, by someone who needs one for his MOV Velocette. It’s nearly thirty years since I had a Velo with a Miller dynamo, and I can’t remember what it was like, except that it couldn’t keep the battery charged when I was riding in the dark, (literally !) We curse Lucas stuff, but Miller was worse. I don’t really blame them, because it was the bike manufacturers who were screwing them down on price all the time, and quality suffered as a result. BTH and Bosch stuff was a lot better.
