Are the ends of that machine orange? That machine does not use cams it has a cam stack adjusted by the lever at the top of the machine. I think it uses class 15 bobbins. You will need to oil it with some tri-flow to free up any knobs or levers which remind me a lot of some of the older Berninas. You may need a lot of patience to get everything moving smoothly. It is not real intuitive to use - caution and patience... I don't know if you can find a manual or not.
