Right, it depends on vintage.
Campagnolo hubs used to come with a 12+ tooth lock ring and cassettes didn't include one.
Lock rings shrunk with the move to 9 cogs in 1997, then expanded from 26 to 27mm with the 1999 over sized aluminum axle, then all hubs used the new lock ring for 2000, and one lock ring would not do the trick for both hub flavors.
IIRC later 11T starting cog cassettes added a lock ring and hubs still came with a 12+ tooth lock ring.
Eventually cassettes all came with lock rings (in the standard 27x1mm format) like Shimano.
