The serial number Jennifer mentions is in the 16 gauge Sterlingworth range. Jennifer, if it is over 350,000 and says Sterlingworth on it, it is not an A Grade, it is a Sterlingworth. Get back on the Fox Collectors site and someone should come up with a Sterlingworth iron for you. Post pictures of the gun so they will know whether your gun takes an extractor forend or an ejector forend. It is more likely an extractor forend. The serial number information given in an earlier post is, unfortunately, a bit off base.
