Hi Jane. Thanks for all the clear info. You have either an S380-26 or S385-26. 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 2530.
