This belonged to my father, who was a guitar maker, during his lifetime. It appears to be the neck of an archtop guitar that has already been sold. I apologize for listing it so late. I overlooked it while organizing my family's workshop. I'm sorry I couldn't offer it as a set to the person who purchased the guitar previously. The joint has been reworked. The headplate laminate is lifting. There are no visible cracks in the neck itself at first glance. The nut is 43mm, and the width at the 14th fret is 55mm. I cannot guarantee that it can be re-joined and used without problems. Please understand that this is a junk item before considering a purchase.
