Hey Dan. This looks like either the S351-29 or S390-29 Channel Balance to me. The only difference between these two balances is the 'depth' of the bottom nylon shoe, or the 'heel-to-toe' measurement. See below for reference. Measure your old balance's shoe depth to see what choices matches best. For a stamp option, choose 2820.
