I've swapped Normandy and Maillard cones a lot of times over the last thirty years, or so. You might be able to find a hub to canniblize at a town dump. There were an awful lot of Normandy hubs on Raliegh, Schwinn, Peugot , Motobecane bikes among others. It might be more difficult to find one with a dust shield, but some dust shields cn be pushed on and off.
