What did the elder book say?
I turned in my elder book just over a month ago. It says nothing about facial hair. It's not a complete rulebook. Generally, where I have been, a brother would be counseled over and over, and if he kept his beard, he would never have any cong. privileges. A Bible student would be expected to shave it off before baptism questions were covered- no room for wavering there.
It is antiquated rules that need to be changed.
