Actually I believe that there are some machines that the bobbins are interchangeable. For example my Singer machines use the same bobbins as my Brother machines I gifted my Janome machine a few years ago so I don't remember but I am pretty sure that I used the same bobbin for them all. Perhaps with newer models that is not the case. I am only speaking of the machines I've owned.
