I'm not sure exactly what you need. That number is sometimes associated with our 15-150D coil support, but this is just a support, not the balance itself. You may also have the 15-111 shoe and Series 160 spring, but I can't be sure. Carefully compare this hardware to your own to confirm if they match.
