There are over 24 reconstructed (Christian, Catholic, Cult) Greek N.T. texts
which do not match in content, volume or doctrine.
The KJV was translated from more than one of those reconstructed Greek NT texts.
The KJV does not follow 100% any one of the varying editions of the Textus Receptus that were available to the KJV translators. The KJV has readings that are found in no Byzantine Greek NT manuscripts. Erasmus produced his reconstructed edition of the Greek text by adding several readings from the Latin Vulgate to it.
