Thanks for posting. It looks like both end attachments lack 'wings', or side tabs. If that is true, see our S351-12 or S390-12 Channel Balance. The only difference between these two balances is the 'depth' of the bottom nylon shoe, or the 'heel-to-toe' measurement. See below. From your photos it looks like your shoe might be 1", but photos of measuring tape are not always reliable, so double and triple-check and see what matches best. For a stamp option choose 1110.
