Rolex case tube help needed…

I have a crown for a Rolex ref. 1803, part number 24-600.

I see there are possibly four case tubes that could work for this crown, but I can’t seem to sort out the differences between them:

24-6000
24-6010
24-6020
24-6030

Would these all work? Is one preferable to another? Many thanks.

Edit: apparently, no 24-6030 exists. 24-6000 has bottom splines, 24-6020, splines on top. What is the 24-6010?
