Vintage Guitar Crazing

[John Arnold]

I think the guitar looks fine as is.
It has oxidation of the wood at the finish cracks. That means that even if the finish checks were re-amalgamated, there still would be dark lines where the checks were.
Even stripping and refinishing would not remove this unless the top is sanded. Sand the top too thin, and sound and structure can be compromised. That is the main reason refinished vintage guitars are valued about half of an original one.
