Can we confirm this at all?

I'm working on my intro essay for volume 2 of Separate Identity. An interview with a long-serving Witness elder has led me to this quest. Sometime between January 1965 and December 1967 The Watchtower's American edition contained an article on marriage specific to Caribbean islands. It was not meant for the American edition and after it was spotted was replaced by another article for the American and international editions. I'm told very few copies circulated.

Do any of you have any details. I cannot use this as is. It's interesting, and if accurate it is illustrative. But until I can trace this down, I cannot use it. Anyone?
