I was looking on Seforim Center a bit earlier to find an edition of the Chofetz Chaim's hilchot tefillin (in Mishnah Berurah chlk. 1, simanim 25-45). I came across a very nicely typeset edition by Oz Vehadar and I was wondering whether it had the author's Mishnat Sofrim which deals with the forms of the Hebrew letters.
Does this, or another nice edition of the M"B include the Mishnat Sofrim?
