I'm out.
Free on the recycling thread from the most gracious @jonsparrow91. The truss rod nut is very badly mangled, but otherwise in good nick.
I have an autumn project in mind and wanted a donor 5 string, so this is it. I will see if I can get some adjustment using a torx key, enough to string it B-G and play it, but the project will need a functional truss rod so I have added "remove fretboard and replace truss rod" to the list.
Of course it's not economically viable, but it will be interesting.
