I immediately noticed the minhag in which he has wrapped the tefillin, and it struck me as a bit odd. It is not the usual Ashkenazi method around the hand.
I'm not an expert on minhagim, but it seems that the "normal" Ashkenazi way of wrapping the tefillin is the Lithuanian minhag. I read a post on A Simple Jew about his minhag from Sudiklov and the hand wrapping looks just like the one in the photo of Berland. (Of course, Berland's tefillin are clearly wrapped inwards per Ashkenazi custom whereas A Simple Jew's are Chassidic and therefore wrap outwards.)
What is the origin of this tefillin wrapping? I have added a photo for convenience. I suspect the minhag might be from Ukraine since Sudiklov (as mentioned in the A Simple Jew blog) is a Ukranian village. Plus, maybe I'm making an assumption that the way R' Moshe Feinstein ztz''l wraps his tefillin is the way all Ashkenazim do.
