What letters actually came from the "Older Men" (aka Governing Body)? Ask a JW that question.
Paul wrote the majority of the letters to the congregations that are recorded in the Bible. He clearly wasn't a member of the Governing Body in Jerusalem even if you buy in to the GB concept!!
In fact, Paul wrote both letters to Timothy, to the Corinthians, to the Ephesians, to the Romans, to the Galatians, to the Philippians, to the Colossians, to the Thessalonians, to Titus, to Philemon, and the book of Hebrews. He clearly wasn't a member of the Governing Body, yet he wrote the vast majority of letters of direction to the congregations!!!! How do JW's not see this??!!
