Gibson 330 Re-visit

I re-fretted this lovely guitar a couple of years ago and it’s come back to me for a once over. There seems to have been a bit of movement so I gave the frets a glance with the levelling bar to ensure everything was spot on. There was a bit of unevenness towards the top which this remedied. The nut had worn too low on the D string and I hoped the brief level would sort this out. It didn’t so I used some dental cement which is as hard as enamel to build up the slot and recut it. The fret board was super dry and was in need of a load of lemon oil.
