This guitar has had restoration work done by notable Bay Area luthier, John Mello. I think the work was done about 20 years ago. Here is what I know about the guitar at this moment, more information will follow soon. I do not see any cracks or crack repairs on this guitar. The ebony bridge and fingerboard have been replaced. The finish is either all oversprayed or refinished. The original tuners are included, new tuners are on the guitar. The tuner holes are not enlarged. The guitar has a newer modern hard case. This is a 1930s 14 fret Martin with a wide nut. It could use some new strings.
