Your wood isn't really cracked.
It's the varnish that cracks.
It is fairly inexpensive to send it out and get it professionally refinished.
There are two guys that specialize in refinishing Mercedes wood: one guy is in California, and the other guy is in North Carolina.
I have seen pieces that have been refinished, and they come back looking absolutely perfect.
Here is a link to the guy that is close to you, Drew at Heritage Woodworks:
