The one to left in post #4 is the last version.
I think Oregon is phasing out 242 clutch drums.
If you have the oil drive with the slots,
the clutch drum you should have is Oregon 40068, Husqvarna's part number is 501.63.66.05.
You can of course go back in time, but I think it's about as hard to find parts then too.
If so, then it's Oregon 29105, you need washer, and the drive was the same one used on 133/234/238/44 and 444, was available in both plastic and bronze.
