Thanks for writing in. Yes, this looks like either an S351-23 or S390-23 Channel Balance. The only difference between these two balances is the 'depth' of the bottom nylon shoe, or the heel-to-toe measurement. See the diagram below for reference. Measure your old balance's shoe depth to see what matches best. For a new stamp option choose 2250.
