I paid $25 for a pair of pump pegs like those and they required a soak in molasses to remove the rust.
The hubs are Normandy Sport. The bike is very similar to a Peugeot PA10. I have one and it's a nice ride. The little bit of extra frame weight over my PX10 is hardly noticeable on flat ground. I've always said that the French had a way with gaspipe frames.
Why aren't your zinc plated spoke crusty and corroded like every other set I've ever seen of that age?
The 72 on the lug is the angle.
