A home owner from CA says:

the measurement in the picture is 27 inches, and there is also a label in the picture, hopefully that can help you to identify the part number.

Hi Junguo. This looks like either an S380-27 or S385-27 . The only difference between these two balances is the depth of the bottom nylon shoe, or 'heel-to-toe' measurement, so compare both with your old hardware to see what matches best. For a new stamp option choose 2630.
