There's this video for "ancient tefillin wrapping" that shows a wrapping style utilizing the paleo-hebrew characters. The statement is that this method of wrapping is preserved by the "Banei Abir clan of Habbani Yemenite Jewry" but i'm not able to find more information about them. Does anyone know more, or have more pictures of this clan of Jews wearing tefillin?
