## Discrepancy

THE CROSSTUBE WAS REMOVED FROM SERVICE DUE TO AN INDICATION OF CORROSION IN THE AREA OF CROSS TUBE TO SKIDTUBE JUNCTURE.  FURTHER INVESTIGATION REVEALED EXCESSIVE CORROSION UNDER THE SADDLES.  THIS OPERATOR VIEWS THIS AS INADEQUATE MANUFACTURING AND REQUESTS SPECIAL WARRANTY CONSIDERATION.  ITEM WAS REPLACED WITH NEW.
