Gershon Dubin asked:
After the point in Bava Basra when "kahn mes Rashi", when Tosfos refer to "the kuntres", whom does he mean?
Gershon
The Kollel replies:
From that point on, Kuntres means Rashbam. The word is always used to refer to the notes that was popularly used, and for the end of Bava Basra it was the Rashbam.
