Jhine: From this site l became aware that the Watchtower that is sold to the public is very different to the study Watchtower.
Could that be a (relatively) recent change? When I was in, the WT was one magazine. The one offered to people in field service was the one we used for the study. But I would be talking about the late 90s, since I started to fade around 1996/7. I didn't realize that they had introduced a different version for the study.
Until last year, I didn't realize they had been producing fewer new magazines, either. I can't say I regret losing touch with them.
