Thanks for posting. This is actually not an Extended-Travel balance. This is one of our standard issue balances; specifically, this appears to be our S380-27 or S385-27 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. For a new stamp option choose, 2630. Comparison of the S380 and S385 balance shoes.
