Beards were a hot topic over here too. Not as a pre baptism rule bt definately for M/S and elders. Latterly I seen one or two in the congo's so I don't think it is as strict as it was (Worldliness gets in everywhere!)
A couple of WT quotes:
* w75 8/15 pp. 500-501 par. 9 Do Not Let Yourself Be Ensnared by Fads and Entertainment *
"*Extreme hair styles can easily lead one into a trap of the Devil also, and cause others to stumble. For example, a young man in the United States was making fine progress in his study of the Bible, and he was moved to share with an experienced Witness in preaching to others about the good things he was learning from the Bible. From early youth he had let his beard grow, and since some in the business community wore beards, he felt that his wearing one in preaching to others would be acceptable generally. But in speaking to a lady he was unable to do more than introduce himself, when she said: "I’m sorry, young man, I do not want to become involved in student revolt." No amount of explanation after this sufficed to clear up the misimpression. After the conversation ended with the closing of the door, he asked the experienced Witness what had happened. He was invited to consider his appearance in relation to what he claimed to be, a servant of God. Not wanting to be responsible for even one person’s being stumbled so as to miss the way to everlasting life, this new Kingdom publisher shaved off his beard. Would you be willing to do the same or to make similar adjustments if your appearance gave the wrong impression in a certain community?"
g00 1/22 p. 24 A Close Shave **[ an Awake article on shavers and shaving]
*"The clean-shaven look continued through the 18th century. But then, by the mid-to-late 19th century, the pendulum began to swing the other way. Hence, photographs of C. T. Russell, the first president of the Watch Tower Society, and fellow Christian W. E. Van Amburgh show both men wearing stylish, well-trimmed beards that were dignified and appropriate for their time. In the early part of the 20th century, however, shaving enjoyed a resurgence of popularity that has endured in most countries to our day."
