A great many use the same design of bobbin winder. It is made to automatically dis-engage when the bobbin is full. I have all of the parts, but I don't know how they are supposed to be assembled. I'm sure it is quite simple, because not many parts are involved. I mounts right next to the hand wheel, rather than being hidden under the top cover.
