I have no idea.
I am looking for Normandy Competition cone hubs and not really having much luck.
There are various suggestions about buying cones for other brands that are a close fit. In the case of
Normandy Competition I haven't heard of a brand that is close.

For Suntour there is Sansin (unless I am confusing it with Sunshine). There is a little more available in the NOS world
although you might have to buy the whole hub to get the cones.
