Balance with ends

Thanks for posting. This might be either an S351-26 or S390-26 Channel Balance. The only difference between these two balances is the depth of the bottom nylon shoe, or its 'heel-to-toe' measurement. See the image below. Compare both with your old balance to see what matches best. In either case, for a new stamp option choose 2540.
