The following link is a pretty good read on Anglo-Israelism, Gentile Times, George Storrs and the Great Pyramid doctrines that Russell taught early on in the Watchtower's history. It would be good for a JW to read this as part of demonstrating how the Watchtower borrowed many of its key doctrines from others who had come along earlier, disproving that they were unique:

It is not written by an apostate or anyone associated with the JWs, but actually by someone in the newly "orthodox" Worldwide Church of God. It mentions Jehovah's Witnesses several times. Get a JW to read it!
