I assume we are talking about the finish cracking or crazing. If you decide to refinish the wood read everything you can about it. Original finish was probably hand rubbed laquer. I have had mixed results on 114s. Main problem was I did not let wood stabilise between steps after chemical stripping I believe. Whatever you do don't sand the wood. You want to preserve the natural patina. Now if wood is bleached out with time you also may want to stain but usually not required. You can do a good job at home but should use a spray gun. Although they can be done without it.
