Thanks for posting. It looks like you have either an S380-27 or S385-27 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, as shown below. Measure your old balance's shoe to see what matches best. In either case, for a new stamp option, choose 2640.
