Right, any Dunlop rims at all will be tricky. Special Lightweights are chromed steel, and not hooked; nice rims, but not even I would pretend they have any advantage; I mention them only because they are the correct original rim for this bike.
I would go for Campy Nuovo Tipo large flange hubs before Normandy, unless you can find the old Normandy hubs with eight round (rather than six kidney shaped) windows in the flange.
The freewheel on my Lenton Grand Prix was pretty worn out, so I used a 14-28 five speed freewheel. As Syke mentioned, there's no way to use all five cogs, so I set it so it wouldn't go into the 14. I found the 16-28 range much more useful than the 14-20 range. They Cyclo derailleur is not supposed to work with a 28T cog, but I had no trouble with that.
Actually, the bike came with the 40 spoke, 8 round hole Normandy on the rear with an alloy rim. Pulled the wheel apart, cleaned up the components and put them on the shelf for the moment. I may rebuild it, and put it back on the bike.
The brakes are the original (I think) Weinmann sidepulls. As I received the bike, it had wrong wheels, was missing the rear derailleur, but otherwise appeared to be complete with the original remaining components.
