It has caged bearings (top of HS on left, bottom on right).
So the first one is a seat for a cartridge and the second is a race for "open" bearings?
Is that just for ease of production, ie assemble just one fork/race and add the race for cheaper models using caged bearings?
Looks like it. I've seen some cheap headsets that are put together like that.
