Even if you can't find the exact model number of your bread machine, I think that a lot of these models operate pretty much the same.
I've never owned a bread machine, and really don't want one. I already own too many kitchen appliances and don't need another one. I have a KitchenAid mixer and it does a great job of mixing ingredients with the dough hook. Once it is mixed, grease a loaf pan, roll out dough, place in pan, let rise, then bake.
