It is part of the collection of David Kaufmann located at the Library of the Hungarian Academy of Sciences in Budapest (MS A50).
It was written in the 10th or 11th century, probably in the land of Israel or perhaps in Italy (the experts disagree).
The manuscript was vocalized a few centuries after the text was written, and the vocalization was introduced from a copy of the Mishnah having a different text than the Kaufmann manuscript.
The author of this vocalization seems to belong to the Sephardic tradition, which sometimes reverses the pataḥ with qamats, and tsere with segol.
