Caldwell 24 3 LQ Balances

Thanks for posting. This looks like either S380-25 or S385-25 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. Compare both with your old hardware to see what matches best. In either case, for a new stamp option choose 2430.
