Yes. Also, the 600 often has an auto-reel bobbin winder which has it's own difficulties. The 603 has the later bobbin winder. After this model, you will find a few 626(?) that have all metal gears, but not many of them do. I got a chance at a 603 a few years ago at an estate sale, but I had another sewing machine in the car already and felt guilty about buying another. I've not seen one since. They are not very common.
