My hunt for angular contact bearings that would fit a Pelissier 2000 hubset was in vein. Nobody I could find makes 10 x 28 x 8 angular contact bearings.
Standard sealed bearings cartridges (16100 Z) have those dimensions as do some "Magneto" bearings. Since Magneto bearings are somewhat angular and designed to be pre-loaded, I'll give them a try. If anyone has a set of Pelissier 2000 hubs, and is willing to open them up and photograph the sideplate of the bearings,
I'd have a better idea if "Magneto" bearings are correct.
