I have measured the balance. It 1/2 inch by 23 inches. The marks on the balance are 22 3 Ko Caldwell. I think that the correct replaceable is the 23" series 385 Channel Balance 2230. Do you agree?

I'm afraid I cannot confirm the Series based on the stamp alone. The S385-23 comes with the 19-005 top and 15-004 bottom. If those match what you have now, then you should be good to go.
