There are two 1/4" presser feet for Bernina machines. #37 is a regular 1/4", and the #57 is the 1/4" with the guide -- it's a metal flange that you guide your fabric against. I prefer the #37, because you can't sew across a diagonal square with the guide, it kinda drags. The 1120 would take the "red box" with the forks at the top of the shaft.
It's a great machine!
