I assume the Frister Rossmann is a low shank, but your 201 accessory box is for the old straight stitchers. Some of the 201 feet will probably work, but for zigzag stitches they neeed the wider needle hole. The feed dogs on the zigzagger is wider set than on a 201, borrowing feet can make things act up in odd ways. The old narrower presser feet doesn't always land ideally on the wider feed dogs. I generally let an old machine keep it's box of accessories. Low shank ruffler feet tend to work on most machines, but I have never needed a ruffle, just tried them out. Adjustable zipper feet should in theory work fine.
