THE NECK IS NOT INCLUDED IN THE SALE. I believe it is the Dan Smith era but could be wrong. Serial number began with E2. I included some photos of them still on the headstock for reference purposes only. All turn smoothly and were clean when removed from the guitar. I did not clean them. One is slightly bent but functions properly (pictured). Measurements are in the last 4 photos. Good communication is the best way to resolve any issue.
