Thanks for posting. It looks like you have either an S380-20 or S385-20. The only difference between these two channel balances is the depth of the bottom nylon shoe, or the 'heel-to-toe' measurement. See the diagram below for reference. Compare both with your old balance to see what matches best. In either case, for a stamp option choose 1930.
