My 1970's era Viking most have a tiny hole on one side which helps me keep the direction straight. I put the hole side on the outside of the bobbin winder and then on the outside of the bobbin case. My vintage Singer has bobbins with holes all around on both sides. My new Janome has a hole on each side that I thread the thread through to get it started. These differences also help me keep the bobbins straight for the different machines. The fact that some are metal and some are plastic helps too except the newer ones I got for my Viking are plastic and look similar to the Janome ones so I have to be careful.
