Your machine looks very nice. I'm sure the bobbin difficulties have to do with correct set up; following the thread rout, guides and hooks correctly or something like that. A winder can act up if there's wheels and turning parts that need cleaning and oiling, rubber tires might need replacing (yours looks fine in the picture though). Make sure it's the correct bobbin for the machine, with old machines the accessories that come with it are often a bunch of all sorts.
