I've been creating some of my own lists and I noticed that Skritter lists both 見 and 西 as Kangxi radical 147.
According to the sources I have checked 西 is 146.
Actually, some sources say that 146 is 襾 and 西 is a variant of that. Skritter doesn't say anything about 襾 being a radical.
Is there a definitive source for Kangxi radicals?
