Welcome to the forum. The picture you posted does not show the serial number. Those are assembly numbers and inspection stamps. The serial number is on the butt of the gun. You may have to remove the grips to see it if it doesnt have the correct factory grips on it

The serial number should also be on the face of the cylinder...its small and on the flat spot under barrel which is covered by the ejector rod with cylinder closed
