Vertical Frame Separation

[ralphbl@mindspring.com]

I have a client who owns a Starck console, circa 1965, that has developed a
separation of the top of the frame (directly behind the pinblock). It's
about 18 inches long and runs from C8 down to about C6. At its widest point,
it's about 1/16th inch (or less) wide. It looks as if there were 2 pieces of
wood glued together to make the top of the frame and they appear to have
separated slightly. I tightened the screws before tuning and discovered that
the RH top corner screw has stripped out. Since I don't do rebuilding, may I
please pick some brains as to whether this is something that needs immediate
attention and/or what would be your ideas for the best procedure?

Thank you,
