We can find C-3PO removable limbs with HK COO and with No COO.
Both LL figures are made out of the typical white plastic and both versions have “Kenner” pendants although this is pretty much unknown.
Both COOs can be found with either a “fat” or a “slim” head. The slim headed ones can be called factory error, because a wrong head – the head from the fixed limbs C-3PO, was accidentally used. For more see: C-3PO
