Here is a better picture of the cams out of white cases even tho some are red both the red and blue ones the depth and width of where it fits measures the same.[/QUOTE]
Hmm, I have no idea what machine they're for. I'm going to guess that the blue cams are for normal single needle sewing and the red cams are for twin needle sewing.
