Guild did not finish those fret ends like that, imo.
Agreed. That is a refret (but a refret done a longer time ago already) that wasn't done well at the edges and with odd shaped fretwire. It hurt my hands from just looking at those 90 deg angled edges of the frets! No real luthier would do that ever.
A factory (or good luthier) done fretboard has proper angled fret ends like on this 1974 one:
This crack number 1 is the neck to body connection of the heal, the lacquer cracks on older guitars, so that is not a big deal. Try to wiggle the neck if the heel is loose or not.
The crack number 2 is the line where the added neck heel piece is glued to the neck and obviously the neck had some kind of impact at some point in time, so a crack developed in the lacquer. I call that more cosmetic, that neck heel will not fall off... Again, wiggle the neck.
