Lack of a truss rod was what made sense to me as to why it is abandoned. If you can make the string height work, you might be able to make it playable, but that would rely entirely on bridge adjustments and maybe shimming it up or setting the bridge deeper in the body.
It already had tuners installed and whatever those were had mounting screws that were offset inboard. The screw holes don't line up across the peg going through the headstock.
Without a picture of the whole back of the neck, I am failing to understand how the different laminated wood pieces in the middle transition to what looks to be on solid piece at the top. Is the headstock also laminated, 90 degrees to neck?
Beautiful wood used in making it! I do woodworking, not on the guitar-making level, though. I would personally have to force myself to see if I could do more to complete this if I found it.
