Another thing that may be worth mentioning is that along with the changes in the bobbin assembly, Singer also changed the face plates to facilitate a change in needle threading. The 15K80 has the face plate thread guide close to the center of the plate for left-to-right needle threading, while the 15-88 has the face plate thread guide on the far right for right-to-left needle threading.
