After picking my Mesa up at Wally I could see a sliver of light between the tang and the scale on one side. I removed the scales to find burrs around the screw holes. I scraped them off sorta countersinking the holes and sanded around the holes with emory paper. That took care of it... no light. The pic was taken before the operation. It looks wider than it actually was because of glare from the flashlight behind it. If anyone else has the problem it is fixable.
