Question: is the AB-3 not available in Belgium? The AB3 seems to be more classic looking than the XRD-3, it was a factory optional hub during the late 40s and early 50s.
If you're fitting a drum brake in the back, what about the front? The front dropouts are spaced for both narrow ~8mm (5/16") axles and hub width (~90mm). The BF hub has slotted axles, and can be spaced down to the ~90mm fork spacing. Like the AB3, it was a factory option available in the 40s and 50s.
The other front drum brake hubs, especially the dynamo/drum brake combined hubs are spaced to 100mm and have 9mm axles, in order to fit them, the fork has to be spread and the dropouts filed (if you are going with this, file on one side only, to keep things aligned.)
