As a strategy it would be good to select two good quotes with the physical copy, one recent and one older. If you only use the old quote they will claim that it's outdated (something they often time do). By using both you will show that they not only have a current policy but have an ongoing one.
Prepare to have a Watchtower CD on hand at the court (though that won't go back to 1952) and a laptop. A physical copy of the 1952 Awake quoted here might help. You need concrete evidence, not just links that they can claim are faked. If you don't have a Watchtower CD I can mail you a 2013 one for free. You can PM me for that.
