What is the height of the current foot on your machine? Measure it sitting it on a flat surface to the top of the shank. Those look like high shank or even super high shank feet. From what I can tell, the feet are a straight stitch foot, a satin stitch foot and 2 open toe clear feet. It looks like parts of a button hole maker. The 2 round things in the plastic bag are extra buttons from a blouse or sweater. If the cams will fit your machine it would be a nice bonus. If the same manufacturer made the machines you should be OK. What are the first 3 numbers in your machine's model number?
