Looking for this 14 5 FR CALDWELL

Hey there. This looks like it might be either the S380-15 or S385-15 Channel Balance. The only difference between these two balances is the 'depth' of the bottom nylon shoe, as shown below. Measure your old balance's shoe depth to see what matches best. For a stamp option choose 1450.
