it this a Series 351 balance?

Question

This is stamped 2730Z. Is the 15-002 shoe that is 1? deep, measured as shown in my last picture?

Greetings! When you measure the bottom nylon shoe, you'll need the "heel to toe" measurement to determine the balance series. Take a look at both the S351-28 that has the 15-002 shoe measuring 1" and the S390-28 with the 15-001 shoe measuring 1-1/8". Compare them to determine which is a better match to yours. For either series, you'll choose the 2730 stamp option. Hope this helps!
