## Discrepancy

COMPRESSION CHECK AT ANNUAL REVEALED CRACKED HEAD-AD 2004-08-10 NA DUE TO SN AND "A" STAMP.  THIS CYLINDER SEEMS TO HAVE SAME PROBLEM AS AD BUT WAS INT INCLUDED.  NOTIFIED MFG.  AD MAY NEED TO BE EXPANDED.  FURTHER TESTING WITH SCRAP AND WATER.  REVEALED 4 MORE CYLINDERS BAD, CYL RETURNED TO MFG FOR WARRANTY OF 50 PERCENT.  AD SHOULD EXTEND TO ALL OF MSB-06-2.
